+@item
+PREAMBLE
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document @dfn{free} in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+
+This License is a kind of ``copyleft'', which means that derivative
+works of the document must themselves be free in the same sense. It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does. But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book. We recommend this License
+principally for works whose purpose is instruction or reference.
+
+@item
+APPLICABILITY AND DEFINITIONS
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License. Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein. The ``Document'', below,
+refers to any such manual or work. Any member of the public is a
+licensee, and is addressed as ``you''. You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+A ``Modified Version'' of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A ``Secondary Section'' is a named appendix or a front-matter section
+of the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall
+subject (or to related matters) and contains nothing that could fall
+directly within that overall subject. (Thus, if the Document is in
+part a textbook of mathematics, a Secondary Section may not explain
+any mathematics.) The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The ``Invariant Sections'' are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License. If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant. The Document may contain zero
+Invariant Sections. If the Document does not identify any Invariant
+Sections then there are none.
+
+The ``Cover Texts'' are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License. A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+A ``Transparent'' copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters. A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text. A copy that is not ``Transparent'' is called ``Opaque''.
+
+Examples of suitable formats for Transparent copies include plain
+ASCII without markup, Texinfo input format, La@TeX{} input
+format, SGML or XML using a publicly available
+DTD, and standard-conforming simple HTML,
+PostScript or PDF designed for human modification. Examples
+of transparent image formats include PNG, XCF and
+JPG. Opaque formats include proprietary formats that can be
+read and edited only by proprietary word processors, SGML or
+XML for which the DTD and/or processing tools are
+not generally available, and the machine-generated HTML,
+PostScript or PDF produced by some word processors for
+output purposes only.
+
+The ``Title Page'' means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page. For works in
+formats which do not have any title page as such, ``Title Page'' means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+The ``publisher'' means any person or entity that distributes copies
+of the Document to the public.
+
+A section ``Entitled XYZ'' means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language. (Here XYZ stands for a
+specific section name mentioned below, such as ``Acknowledgements'',
+``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title''
+of such a section when you modify the Document means that it remains a
+section ``Entitled XYZ'' according to this definition.
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document. These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+
+@item
+VERBATIM COPYING
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License. You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute. However, you may accept
+compensation in exchange for copies. If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+@item
+COPYING IN QUANTITY
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover. Both covers must also clearly and legibly identify
+you as the publisher of these copies. The front cover must present
+the full title with all words of the title equally prominent and
+visible. You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+
+@item
+MODIFICATIONS
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it. In addition, you must do these things in the Modified Version:
+
+@enumerate A
+@item
+Use in the Title Page (and on the covers, if any) a title distinct
+from that of the Document, and from those of previous versions
+(which should, if there were any, be listed in the History section
+of the Document). You may use the same title as a previous version
+if the original publisher of that version gives permission.
+
+@item
+List on the Title Page, as authors, one or more persons or entities
+responsible for authorship of the modifications in the Modified
+Version, together with at least five of the principal authors of the
+Document (all of its principal authors, if it has fewer than five),
+unless they release you from this requirement.
+
+@item
+State on the Title page the name of the publisher of the
+Modified Version, as the publisher.
+
+@item
+Preserve all the copyright notices of the Document.
+
+@item
+Add an appropriate copyright notice for your modifications
+adjacent to the other copyright notices.
+
+@item
+Include, immediately after the copyright notices, a license notice
+giving the public permission to use the Modified Version under the
+terms of this License, in the form shown in the Addendum below.
+
+@item
+Preserve in that license notice the full lists of Invariant Sections
+and required Cover Texts given in the Document's license notice.
+
+@item
+Include an unaltered copy of this License.
+
+@item
+Preserve the section Entitled ``History'', Preserve its Title, and add
+to it an item stating at least the title, year, new authors, and
+publisher of the Modified Version as given on the Title Page. If
+there is no section Entitled ``History'' in the Document, create one
+stating the title, year, authors, and publisher of the Document as
+given on its Title Page, then add an item describing the Modified
+Version as stated in the previous sentence.
+
+@item
+Preserve the network location, if any, given in the Document for
+public access to a Transparent copy of the Document, and likewise
+the network locations given in the Document for previous versions
+it was based on. These may be placed in the ``History'' section.
+You may omit a network location for a work that was published at
+least four years before the Document itself, or if the original
+publisher of the version it refers to gives permission.
+
+@item
+For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
+the Title of the section, and preserve in the section all the
+substance and tone of each of the contributor acknowledgements and/or
+dedications given therein.
+
+@item
+Preserve all the Invariant Sections of the Document,
+unaltered in their text and in their titles. Section numbers
+or the equivalent are not considered part of the section titles.
+
+@item
+Delete any section Entitled ``Endorsements''. Such a section
+may not be included in the Modified Version.
+
+@item
+Do not retitle any existing section to be Entitled ``Endorsements'' or
+to conflict in title with any Invariant Section.
+
+@item
+Preserve any Warranty Disclaimers.
+@end enumerate
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant. To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section Entitled ``Endorsements'', provided it contains
+nothing but endorsements of your Modified Version by various
+parties---for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version. Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity. If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+@item
+COMBINING DOCUMENTS
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy. If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled ``History''
+in the various original documents, forming one section Entitled
+``History''; likewise combine any sections Entitled ``Acknowledgements'',
+and any sections Entitled ``Dedications''. You must delete all
+sections Entitled ``Endorsements.''
+
+@item
+COLLECTIONS OF DOCUMENTS
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+@item
+AGGREGATION WITH INDEPENDENT WORKS
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an ``aggregate'' if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+@item
+TRANSLATION
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections. You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers. In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+If a section in the Document is Entitled ``Acknowledgements'',
+``Dedications'', or ``History'', the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+@item
+TERMINATION
+
+You may not copy, modify, sublicense, or distribute the Document
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense, or distribute it is void, and
+will automatically terminate your rights under this License.
+
+However, if you cease all violation of this License, then your license
+from a particular copyright holder is reinstated (a) provisionally,
+unless and until the copyright holder explicitly and finally
+terminates your license, and (b) permanently, if the copyright holder
+fails to notify you of the violation by some reasonable means prior to
+60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, receipt of a copy of some or all of the same material does
+not give you any rights to use it.
+
+@item
+FUTURE REVISIONS OF THIS LICENSE
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns. See
+@uref{http://www.gnu.org/copyleft/}.
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License ``or any later version'' applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation. If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation. If the Document
+specifies that a proxy can decide which future versions of this
+License can be used, that proxy's public statement of acceptance of a
+version permanently authorizes you to choose that version for the
+Document.
+
+@item
+RELICENSING
+
+``Massive Multiauthor Collaboration Site'' (or ``MMC Site'') means any
+World Wide Web server that publishes copyrightable works and also
+provides prominent facilities for anybody to edit those works. A
+public wiki that anybody can edit is an example of such a server. A
+``Massive Multiauthor Collaboration'' (or ``MMC'') contained in the
+site means any set of copyrightable works thus published on the MMC
+site.
+
+``CC-BY-SA'' means the Creative Commons Attribution-Share Alike 3.0
+license published by Creative Commons Corporation, a not-for-profit
+corporation with a principal place of business in San Francisco,
+California, as well as future copyleft versions of that license
+published by that same organization.
+
+``Incorporate'' means to publish or republish a Document, in whole or
+in part, as part of another Document.
+
+An MMC is ``eligible for relicensing'' if it is licensed under this
+License, and if all works that were first published under this License
+somewhere other than this MMC, and subsequently incorporated in whole
+or in part into the MMC, (1) had no cover texts or invariant sections,
+and (2) were thus incorporated prior to November 1, 2008.
+
+The operator of an MMC Site may republish an MMC contained in the site
+under CC-BY-SA on the same site at any time before August 1, 2009,
+provided the MMC is eligible for relicensing.

+1 Overview
+**********
+
+GNU LibreJS --an add-on for GNU IceCat and Mozilla Firefox-- detects and
+blocks nonfree nontrivial JavaScript while allowing its execution on
+pages containing code that is either trivial and/or free.
+
+ Many websites run nontrivial JavaScript on your computer. Some use
+it for complex tasks; many use it gratuitously for minor jobs that could
+be done easily with plain HTML. Sometimes this JavaScript code is
+malicious. Either way, the JavaScript code is often nonfree. For
+explanation of the issue, see "The JavaScript
+Trap"(<http://www.gnu.org/philosophy/javascript-trap.html>).
+
+ If you care about freedom in your computing, and don't wish to let
+all and sundry make you run nonfree programs, now you can prevent it by
+using LibreJS.

+2 Disclaimer
+************
+
+ * LibreJS is not a security tool. Its goal is to detect nonfree
+ nontrivial JavaScript, and it currently does not detect whether
+ free or trivial code is malicious or not. Other free Mozilla
+ extensions and add-ons may be available for this purpose.
+
+ * LibreJS is always a work in progress. If you find a bug, please
+ report it to <bug-librejs@gnu.org>.

+3 Installation
+**************
+
+You can install LibreJS directly using a generated 'librejs.xpi' file,
+or by building it from source.
+
+ You can also download it from Mozilla, but due to Mozilla's review
+process the download isn't always up to date.
+
+
+File: librejs.info, Node: How to Use, Next: JavaScript Detection, Prev: Installation, Up: Top
+
+4 How to Use
+************
+
+4.1 LibreJS in action
+=====================
+
+After installing the add-on, you will see the LibreJS widget in the
+add-on bar at the top right of the browser window. After loading a
+page, left-click on the widget to view the deactivated JavaScript code
+from the page (both on page and external) and, if applicable, the
+scripts that were accepted.
+
+4.2 Script Blacklist/whitelist
+==============================
+
+Scripts may be blacklisted or whitelisted through the pop-up menu box.
+
+ Whitelisted scripts will always be accepted and blacklisted scripts
+will always get rejected.
+
+ It is important to note that this feature recognizes which scripts
+are blacklisted and whitelisted based on hash. This means that even a
+slight difference in a script's code will cause it to be recognized as a
+seperate script.
+
+ Sometimes, JavaScript will be dynamically generated so that it is
+different every time a website is loaded. These types of scripts cannot
+be whitelisted or blacklisted since they cannot be recognized.
+
+ LibreJS has a default whitelist of scripts that are known to be free
+but may not use the format for declaring a license that it can
+understand.
+
+4.3 Complaint Feature
+=====================
+
+It is very important to complain when a site has nonfree JavaScript
+code, especially if it won't work without that code. LibreJS makes it
+easy to complain by heuristically finding where to send the complaint.
+
+ When nonfree/nontrivial code is detected in a page, LibreJS attempts
+to find a relevant contact link or email for the website you are
+visiting. In order to do so, it will attempt to visit a few links from
+the current page (for instance, a link labeled "contact" on the same
+domain as the current page, ...)
+
+ LibreJS detects contact pages, email addresses that are likely to be
+owned by the maintainer of the site, Twitter and identi.ca links, and
+phone numbers.
+
+ When you complain to the website for their nonfree nontrivial
+JavaScript, provide them with the link to the JavaScript Trap essay so
+that they can get more information on what the issue is and how they can
+solve it on their own site.
+
+ LibreJS includes a default subject line and body for the complaint
+email, with a link to the JavaScript Trap essay. This can be configured
+in the LibreJS add-on preferences in your web browser.
+
+4.4 Options
+===========
+
+"Whitelist"
+
+ LibreJS lets you whitelist domain names and subdomains to bypass
+ the regular JavaScript check. This might be useful, for example,
+ if you are running your own code in a local web server. In order
+ to add a whitelisted domain or url, go to Tools >> Add-ons. Inside
+ the add-on window, click on "Extensions", and in the list, where
+ you see LibreJS, click on the "Preferences" button. You will see
+ an input field labeled "Whitelist".
+
+ In the field, enter comma-separated domain names. Do not enter the
+ protocol. For instance to whitelist all the pages of
+ <http://www.gnu.org> and <https://gnu.org>, enter 'gnu.org'. To
+ allow all subdomains from gnu.org, enter: '*.gnu.org'. This will
+ match such sites as <http://savannah.gnu.org> and
+ <http://audio-video.gnu.org>.
+
+"Complaint email subject"
+ Configure the default subject used in complaint emails.
+
+"Complaint email body"
+ Configure the default body used in complaint emails.

+5 JavaScript Detection
+**********************
+
+LibreJS considers a very strict subset of JavaScript to be acceptable
+for use in non-free scripts. This is meant to maximimize compatibility
+with websites that haven't tried to be LibreJS compatible.
+
+ We consider modification of the document non-trivial. There isn't
+much that javascript could do that we would consider trivial, for
+anything else a free software license would be required.
+
+ The criterion is as follows:
+
+ For each function definition:
+ * It must call only primitives.
+ * The number of conditionals and loops must be at most 3.
+ * It does not declare an array more than 50 elements long.
+ * It must not call itself
+
+ For the rest of the script, outside of function definitions:
+ * It must call only primitives and functions defined above in the
+ page.
+ * The number of conditionals and loops must be at most 3.
+
+ "function" means anything executable that gets a name, including
+methods.
+
+ Allowed primitives exclude:
+ * eval()
+ * ajax
+ * calling methods with the square bracket notation
+ * altering the dom
+ * most other items found as methods of the '.window' object.

+6 Free Licenses Detection
+*************************
+
+The machine readable format for license declarations that LibreJS uses
+has changed in the most recent version. This was necessary in order to
+not break the asynchronous JS loading model that browsers use. Scripts
+are now evaluated independent of eachother and strictly as they arrive.

+
+7 Setting Your JavaScript Free
+******************************
+
+The first step is releasing your JavaScript under a free license. If
+you are already using a free library, or you're not using any
+third-party libraries, it might only take a few minutes.
+
+ On your website, take a look at your HTML source. You can identify
+distinct pieces of JavaScript that might be free and some other that are
+nonfree.
+
+ This might be the case with an analytics tracker, social media
+widgets, and code that runs ads. Removing these pieces of code from
+your site is required to have the rest accepted as free. There are
+often alternatives to nonfree libraries or to third-party services:
+
+ * If you have used nonfree third-party code as the base to write your
+ own code, try to find a free alternative.
+
+ * If you're using a third-party service such as an analytics service,
+ replace it with a free alternative like Piwik.
+
+ * If you can't find free JavaScript that has already been developed,
+ write it yourself! Who knows, your own solution might be the start
+ of a brilliant project!
+
+7.1 License tags
+================
+
+LibreJS will allow non-trivial scripts to run as long as they use a free
+license.
+
+ In order for the license of a script to be recognized by LibreJS, it
+must be declared using a machine-readable license format.
+
+ This format is the same for both remote in-line scripts.
+
+ "// @license [magnet link] [identifier]" [Script here] "//
+@license-end"
+
+ "Identifier" is a name of a license from the following list and
+"magnet link" is that license's exact corresponding magnet link.

+8 LibreJS Development Notes
+***************************
+
+8.1 Debugging
+=============
+
+To debug LibreJS, visit the special URL 'about:debugging'. Click on
+'Enable add-on debugging' then 'Load Temporary Add-on'. Navigate to
+LibreJS's unpacked source directory and select 'manifest.json'.
+
+ Lines 34 and 35 in 'main_background.js' control the printing of
+'dbg_print()' statements. Make sure these are set to false in releases.
+
+8.2 Adding new whitelisted libraries
+====================================
+
+The script index.js in './hash_script' generates the default whitelist.
+Run it with the following command:
+
+ 'node index.js > output'
+
+ Then, just copy the contents of the file "output" to the appropriate
+place in main_background.js.
+
+8.3 Releasing a new version
+===========================
+
+Update the version number in manifest.json.
+
+ Make sure debug statements are set to felse on lines 34/35 in
+'main_background.js'.
+
+ Then, run the build script 'build.sh'.

+A.1 Mozilla Browser
+===================
+
+You will need one of the many flavors of the Mozilla browser to use
+LibreJS. It can be installed on the following:
+
+ GNU IceCat, Mozilla Firefox, Trisquel Abrowser, Debian Iceweasel.
+
+ LibreJS works on these browsers starting from version 57. We
+recommend that you use the latest version of your Mozilla browser.
+LibreJS has been tested on a GNU/Linux distribution, but it is
+compatible any operating system as long as you're using a compatible
+Mozilla browser.

+Appendix B LibreJS Internals
+****************************
+
+LibreJS intercepts HTTP responses and rewrites their contents after
+analyzing JavaScript within them. It does not remove script nodes and
+attributes from the page, but instead "deactivates" them by replacing
+their content with a commented notice.
+
+ LibreJS detects the most common cases using the HTTP response method
+described above, but in less common edge cases, or when running code
+locally, LibreJS cannot detect JavaScript during the response stage.

+ Version 1.3, 3 November 2008
+
+ Copyright (C) 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.
+ <http://fsf.org/>
+
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ 0. PREAMBLE
+
+ The purpose of this License is to make a manual, textbook, or other
+ functional and useful document "free" in the sense of freedom: to
+ assure everyone the effective freedom to copy and redistribute it,
+ with or without modifying it, either commercially or
+ noncommercially. Secondarily, this License preserves for the
+ author and publisher a way to get credit for their work, while not
+ being considered responsible for modifications made by others.
+
+ This License is a kind of "copyleft", which means that derivative
+ works of the document must themselves be free in the same sense.
+ It complements the GNU General Public License, which is a copyleft
+ license designed for free software.
+
+ We have designed this License in order to use it for manuals for
+ free software, because free software needs free documentation: a
+ free program should come with manuals providing the same freedoms
+ that the software does. But this License is not limited to
+ software manuals; it can be used for any textual work, regardless
+ of subject matter or whether it is published as a printed book. We
+ recommend this License principally for works whose purpose is
+ instruction or reference.
+
+ 1. APPLICABILITY AND DEFINITIONS
+
+ This License applies to any manual or other work, in any medium,
+ that contains a notice placed by the copyright holder saying it can
+ be distributed under the terms of this License. Such a notice
+ grants a world-wide, royalty-free license, unlimited in duration,
+ to use that work under the conditions stated herein. The
+ "Document", below, refers to any such manual or work. Any member
+ of the public is a licensee, and is addressed as "you". You accept
+ the license if you copy, modify or distribute the work in a way
+ requiring permission under copyright law.
+
+ A "Modified Version" of the Document means any work containing the
+ Document or a portion of it, either copied verbatim, or with
+ modifications and/or translated into another language.
+
+ A "Secondary Section" is a named appendix or a front-matter section
+ of the Document that deals exclusively with the relationship of the
+ publishers or authors of the Document to the Document's overall
+ subject (or to related matters) and contains nothing that could
+ fall directly within that overall subject. (Thus, if the Document
+ is in part a textbook of mathematics, a Secondary Section may not
+ explain any mathematics.) The relationship could be a matter of
+ historical connection with the subject or with related matters, or
+ of legal, commercial, philosophical, ethical or political position
+ regarding them.
+
+ The "Invariant Sections" are certain Secondary Sections whose
+ titles are designated, as being those of Invariant Sections, in the
+ notice that says that the Document is released under this License.
+ If a section does not fit the above definition of Secondary then it
+ is not allowed to be designated as Invariant. The Document may
+ contain zero Invariant Sections. If the Document does not identify
+ any Invariant Sections then there are none.
+
+ The "Cover Texts" are certain short passages of text that are
+ listed, as Front-Cover Texts or Back-Cover Texts, in the notice
+ that says that the Document is released under this License. A
+ Front-Cover Text may be at most 5 words, and a Back-Cover Text may
+ be at most 25 words.
+
+ A "Transparent" copy of the Document means a machine-readable copy,
+ represented in a format whose specification is available to the
+ general public, that is suitable for revising the document
+ straightforwardly with generic text editors or (for images composed
+ of pixels) generic paint programs or (for drawings) some widely
+ available drawing editor, and that is suitable for input to text
+ formatters or for automatic translation to a variety of formats
+ suitable for input to text formatters. A copy made in an otherwise
+ Transparent file format whose markup, or absence of markup, has
+ been arranged to thwart or discourage subsequent modification by
+ readers is not Transparent. An image format is not Transparent if
+ used for any substantial amount of text. A copy that is not
+ "Transparent" is called "Opaque".
+
+ Examples of suitable formats for Transparent copies include plain
+ ASCII without markup, Texinfo input format, LaTeX input format,
+ SGML or XML using a publicly available DTD, and standard-conforming
+ simple HTML, PostScript or PDF designed for human modification.
+ Examples of transparent image formats include PNG, XCF and JPG.
+ Opaque formats include proprietary formats that can be read and
+ edited only by proprietary word processors, SGML or XML for which
+ the DTD and/or processing tools are not generally available, and
+ the machine-generated HTML, PostScript or PDF produced by some word
+ processors for output purposes only.
+
+ The "Title Page" means, for a printed book, the title page itself,
+ plus such following pages as are needed to hold, legibly, the
+ material this License requires to appear in the title page. For
+ works in formats which do not have any title page as such, "Title
+ Page" means the text near the most prominent appearance of the
+ work's title, preceding the beginning of the body of the text.
+
+ The "publisher" means any person or entity that distributes copies
+ of the Document to the public.
+
+ A section "Entitled XYZ" means a named subunit of the Document
+ whose title either is precisely XYZ or contains XYZ in parentheses
+ following text that translates XYZ in another language. (Here XYZ
+ stands for a specific section name mentioned below, such as
+ "Acknowledgements", "Dedications", "Endorsements", or "History".)
+ To "Preserve the Title" of such a section when you modify the
+ Document means that it remains a section "Entitled XYZ" according
+ to this definition.
+
+ The Document may include Warranty Disclaimers next to the notice
+ which states that this License applies to the Document. These
+ Warranty Disclaimers are considered to be included by reference in
+ this License, but only as regards disclaiming warranties: any other
+ implication that these Warranty Disclaimers may have is void and
+ has no effect on the meaning of this License.
+
+ 2. VERBATIM COPYING
+
+ You may copy and distribute the Document in any medium, either
+ commercially or noncommercially, provided that this License, the
+ copyright notices, and the license notice saying this License
+ applies to the Document are reproduced in all copies, and that you
+ add no other conditions whatsoever to those of this License. You
+ may not use technical measures to obstruct or control the reading
+ or further copying of the copies you make or distribute. However,
+ you may accept compensation in exchange for copies. If you
+ distribute a large enough number of copies you must also follow the
+ conditions in section 3.
+
+ You may also lend copies, under the same conditions stated above,
+ and you may publicly display copies.
+
+ 3. COPYING IN QUANTITY
+
+ If you publish printed copies (or copies in media that commonly
+ have printed covers) of the Document, numbering more than 100, and
+ the Document's license notice requires Cover Texts, you must
+ enclose the copies in covers that carry, clearly and legibly, all
+ these Cover Texts: Front-Cover Texts on the front cover, and
+ Back-Cover Texts on the back cover. Both covers must also clearly
+ and legibly identify you as the publisher of these copies. The
+ front cover must present the full title with all words of the title
+ equally prominent and visible. You may add other material on the
+ covers in addition. Copying with changes limited to the covers, as
+ long as they preserve the title of the Document and satisfy these
+ conditions, can be treated as verbatim copying in other respects.
+
+ If the required texts for either cover are too voluminous to fit
+ legibly, you should put the first ones listed (as many as fit
+ reasonably) on the actual cover, and continue the rest onto
+ adjacent pages.
+
+ If you publish or distribute Opaque copies of the Document
+ numbering more than 100, you must either include a machine-readable
+ Transparent copy along with each Opaque copy, or state in or with
+ each Opaque copy a computer-network location from which the general
+ network-using public has access to download using public-standard
+ network protocols a complete Transparent copy of the Document, free
+ of added material. If you use the latter option, you must take
+ reasonably prudent steps, when you begin distribution of Opaque
+ copies in quantity, to ensure that this Transparent copy will
+ remain thus accessible at the stated location until at least one
+ year after the last time you distribute an Opaque copy (directly or
+ through your agents or retailers) of that edition to the public.
+
+ It is requested, but not required, that you contact the authors of
+ the Document well before redistributing any large number of copies,
+ to give them a chance to provide you with an updated version of the
+ Document.
+
+ 4. MODIFICATIONS
+
+ You may copy and distribute a Modified Version of the Document
+ under the conditions of sections 2 and 3 above, provided that you
+ release the Modified Version under precisely this License, with the
+ Modified Version filling the role of the Document, thus licensing
+ distribution and modification of the Modified Version to whoever
+ possesses a copy of it. In addition, you must do these things in
+ the Modified Version:
+
+ A. Use in the Title Page (and on the covers, if any) a title
+ distinct from that of the Document, and from those of previous
+ versions (which should, if there were any, be listed in the
+ History section of the Document). You may use the same title
+ as a previous version if the original publisher of that
+ version gives permission.
+
+ B. List on the Title Page, as authors, one or more persons or
+ entities responsible for authorship of the modifications in
+ the Modified Version, together with at least five of the
+ principal authors of the Document (all of its principal
+ authors, if it has fewer than five), unless they release you
+ from this requirement.
+
+ C. State on the Title page the name of the publisher of the
+ Modified Version, as the publisher.
+
+ D. Preserve all the copyright notices of the Document.
+
+ E. Add an appropriate copyright notice for your modifications
+ adjacent to the other copyright notices.
+
+ F. Include, immediately after the copyright notices, a license
+ notice giving the public permission to use the Modified
+ Version under the terms of this License, in the form shown in
+ the Addendum below.
+
+ G. Preserve in that license notice the full lists of Invariant
+ Sections and required Cover Texts given in the Document's
+ license notice.
+
+ H. Include an unaltered copy of this License.
+
+ I. Preserve the section Entitled "History", Preserve its Title,
+ and add to it an item stating at least the title, year, new
+ authors, and publisher of the Modified Version as given on the
+ Title Page. If there is no section Entitled "History" in the
+ Document, create one stating the title, year, authors, and
+ publisher of the Document as given on its Title Page, then add
+ an item describing the Modified Version as stated in the
+ previous sentence.
+
+ J. Preserve the network location, if any, given in the Document
+ for public access to a Transparent copy of the Document, and
+ likewise the network locations given in the Document for
+ previous versions it was based on. These may be placed in the
+ "History" section. You may omit a network location for a work
+ that was published at least four years before the Document
+ itself, or if the original publisher of the version it refers
+ to gives permission.
+
+ K. For any section Entitled "Acknowledgements" or "Dedications",
+ Preserve the Title of the section, and preserve in the section
+ all the substance and tone of each of the contributor
+ acknowledgements and/or dedications given therein.
+
+ L. Preserve all the Invariant Sections of the Document, unaltered
+ in their text and in their titles. Section numbers or the
+ equivalent are not considered part of the section titles.
+
+ M. Delete any section Entitled "Endorsements". Such a section
+ may not be included in the Modified Version.
+
+ N. Do not retitle any existing section to be Entitled
+ "Endorsements" or to conflict in title with any Invariant
+ Section.
+
+ O. Preserve any Warranty Disclaimers.
+
+ If the Modified Version includes new front-matter sections or
+ appendices that qualify as Secondary Sections and contain no
+ material copied from the Document, you may at your option designate
+ some or all of these sections as invariant. To do this, add their
+ titles to the list of Invariant Sections in the Modified Version's
+ license notice. These titles must be distinct from any other
+ section titles.
+
+ You may add a section Entitled "Endorsements", provided it contains
+ nothing but endorsements of your Modified Version by various
+ parties--for example, statements of peer review or that the text
+ has been approved by an organization as the authoritative
+ definition of a standard.
+
+ You may add a passage of up to five words as a Front-Cover Text,
+ and a passage of up to 25 words as a Back-Cover Text, to the end of
+ the list of Cover Texts in the Modified Version. Only one passage
+ of Front-Cover Text and one of Back-Cover Text may be added by (or
+ through arrangements made by) any one entity. If the Document
+ already includes a cover text for the same cover, previously added
+ by you or by arrangement made by the same entity you are acting on
+ behalf of, you may not add another; but you may replace the old
+ one, on explicit permission from the previous publisher that added
+ the old one.
+
+ The author(s) and publisher(s) of the Document do not by this
+ License give permission to use their names for publicity for or to
+ assert or imply endorsement of any Modified Version.
+
+ 5. COMBINING DOCUMENTS
+
+ You may combine the Document with other documents released under
+ this License, under the terms defined in section 4 above for
+ modified versions, provided that you include in the combination all
+ of the Invariant Sections of all of the original documents,
+ unmodified, and list them all as Invariant Sections of your
+ combined work in its license notice, and that you preserve all
+ their Warranty Disclaimers.
+
+ The combined work need only contain one copy of this License, and
+ multiple identical Invariant Sections may be replaced with a single
+ copy. If there are multiple Invariant Sections with the same name
+ but different contents, make the title of each such section unique
+ by adding at the end of it, in parentheses, the name of the
+ original author or publisher of that section if known, or else a
+ unique number. Make the same adjustment to the section titles in
+ the list of Invariant Sections in the license notice of the
+ combined work.
+
+ In the combination, you must combine any sections Entitled
+ "History" in the various original documents, forming one section
+ Entitled "History"; likewise combine any sections Entitled
+ "Acknowledgements", and any sections Entitled "Dedications". You
+ must delete all sections Entitled "Endorsements."
+
+ 6. COLLECTIONS OF DOCUMENTS
+
+ You may make a collection consisting of the Document and other
+ documents released under this License, and replace the individual
+ copies of this License in the various documents with a single copy
+ that is included in the collection, provided that you follow the
+ rules of this License for verbatim copying of each of the documents
+ in all other respects.
+
+ You may extract a single document from such a collection, and
+ distribute it individually under this License, provided you insert
+ a copy of this License into the extracted document, and follow this
+ License in all other respects regarding verbatim copying of that
+ document.
+
+ 7. AGGREGATION WITH INDEPENDENT WORKS
+
+ A compilation of the Document or its derivatives with other
+ separate and independent documents or works, in or on a volume of a
+ storage or distribution medium, is called an "aggregate" if the
+ copyright resulting from the compilation is not used to limit the
+ legal rights of the compilation's users beyond what the individual
+ works permit. When the Document is included in an aggregate, this
+ License does not apply to the other works in the aggregate which
+ are not themselves derivative works of the Document.
+
+ If the Cover Text requirement of section 3 is applicable to these
+ copies of the Document, then if the Document is less than one half
+ of the entire aggregate, the Document's Cover Texts may be placed
+ on covers that bracket the Document within the aggregate, or the
+ electronic equivalent of covers if the Document is in electronic
+ form. Otherwise they must appear on printed covers that bracket
+ the whole aggregate.
+
+ 8. TRANSLATION
+
+ Translation is considered a kind of modification, so you may
+ distribute translations of the Document under the terms of section
+ 4. Replacing Invariant Sections with translations requires special
+ permission from their copyright holders, but you may include
+ translations of some or all Invariant Sections in addition to the
+ original versions of these Invariant Sections. You may include a
+ translation of this License, and all the license notices in the
+ Document, and any Warranty Disclaimers, provided that you also
+ include the original English version of this License and the
+ original versions of those notices and disclaimers. In case of a
+ disagreement between the translation and the original version of
+ this License or a notice or disclaimer, the original version will
+ prevail.
+
+ If a section in the Document is Entitled "Acknowledgements",
+ "Dedications", or "History", the requirement (section 4) to
+ Preserve its Title (section 1) will typically require changing the
+ actual title.
+
+ 9. TERMINATION
+
+ You may not copy, modify, sublicense, or distribute the Document
+ except as expressly provided under this License. Any attempt
+ otherwise to copy, modify, sublicense, or distribute it is void,
+ and will automatically terminate your rights under this License.
+
+ However, if you cease all violation of this License, then your
+ license from a particular copyright holder is reinstated (a)
+ provisionally, unless and until the copyright holder explicitly and
+ finally terminates your license, and (b) permanently, if the
+ copyright holder fails to notify you of the violation by some
+ reasonable means prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+ reinstated permanently if the copyright holder notifies you of the
+ violation by some reasonable means, this is the first time you have
+ received notice of violation of this License (for any work) from
+ that copyright holder, and you cure the violation prior to 30 days
+ after your receipt of the notice.
+
+ Termination of your rights under this section does not terminate
+ the licenses of parties who have received copies or rights from you
+ under this License. If your rights have been terminated and not
+ permanently reinstated, receipt of a copy of some or all of the
+ same material does not give you any rights to use it.
+
+ 10. FUTURE REVISIONS OF THIS LICENSE
+
+ The Free Software Foundation may publish new, revised versions of
+ the GNU Free Documentation License from time to time. Such new
+ versions will be similar in spirit to the present version, but may
+ differ in detail to address new problems or concerns. See
+ <http://www.gnu.org/copyleft/>.
+
+ Each version of the License is given a distinguishing version
+ number. If the Document specifies that a particular numbered
+ version of this License "or any later version" applies to it, you
+ have the option of following the terms and conditions either of
+ that specified version or of any later version that has been
+ published (not as a draft) by the Free Software Foundation. If the
+ Document does not specify a version number of this License, you may
+ choose any version ever published (not as a draft) by the Free
+ Software Foundation. If the Document specifies that a proxy can
+ decide which future versions of this License can be used, that
+ proxy's public statement of acceptance of a version permanently
+ authorizes you to choose that version for the Document.
+
+ 11. RELICENSING
+
+ "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
+ World Wide Web server that publishes copyrightable works and also
+ provides prominent facilities for anybody to edit those works. A
+ public wiki that anybody can edit is an example of such a server.
+ A "Massive Multiauthor Collaboration" (or "MMC") contained in the
+ site means any set of copyrightable works thus published on the MMC
+ site.
+
+ "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
+ license published by Creative Commons Corporation, a not-for-profit
+ corporation with a principal place of business in San Francisco,
+ California, as well as future copyleft versions of that license
+ published by that same organization.
+
+ "Incorporate" means to publish or republish a Document, in whole or
+ in part, as part of another Document.
+
+ An MMC is "eligible for relicensing" if it is licensed under this
+ License, and if all works that were first published under this
+ License somewhere other than this MMC, and subsequently
+ incorporated in whole or in part into the MMC, (1) had no cover
+ texts or invariant sections, and (2) were thus incorporated prior
+ to November 1, 2008.
+
+ The operator of an MMC Site may republish an MMC contained in the
+ site under CC-BY-SA on the same site at any time before August 1,
+ 2009, provided the MMC is eligible for relicensing.
+
+ADDENDUM: How to use this License for your documents
+====================================================
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and license
+notices just after the title page:
+
+ Copyright (C) YEAR YOUR NAME.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.3
+ or any later version published by the Free Software Foundation;
+ with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+ Texts. A copy of the license is included in the section entitled ``GNU
+ Free Documentation License''.
+
+ If you have Invariant Sections, Front-Cover Texts and Back-Cover
+Texts, replace the "with...Texts." line with this:
+
+ with the Invariant Sections being LIST THEIR TITLES, with
+ the Front-Cover Texts being LIST, and with the Back-Cover Texts
+ being LIST.
+
+ If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+ If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of free
+software license, such as the GNU General Public License, to permit
+their use in free software.

+
+@cindex overview
+GNU LibreJS ---an add-on for GNU IceCat and Mozilla Firefox--- detects
+and blocks nonfree nontrivial JavaScript while allowing its execution on
+pages containing code that is either trivial and/or free.
+
+Many websites run nontrivial JavaScript on your computer. Some use it
+for complex tasks; many use it gratuitously for minor jobs that could be
+done easily with plain HTML. Sometimes this JavaScript code is
+malicious. Either way, the JavaScript code is often nonfree. For
+explanation of the issue, see "The JavaScript
+Trap"(@url{http://www.gnu.org/philosophy/javascript-trap.html}).
+
+If you care about freedom in your computing, and don't wish to let all
+and sundry make you run nonfree programs, now you can prevent it by
+using LibreJS.
+
+
+@node Disclaimer
+@chapter Disclaimer
+
+@cindex disclaimer
+
+@itemize @bullet
+@item
+LibreJS is not a security tool. Its goal is to detect nonfree nontrivial
+JavaScript, and it currently does not detect whether free or trivial
+code is malicious or not. Other free Mozilla extensions and add-ons may
+be available for this purpose.
+
+@item
+LibreJS is always a work in progress. If you find a bug, please report
+it to @email{bug-librejs@@gnu.org}.
+
+@end itemize
+
+@node Installation
+@chapter Installation
+@cindex Installation
+
+You can install LibreJS directly using a generated @file{librejs.xpi}
+file, or by building it from source.
+
+You can also download it from Mozilla, but due to Mozilla's review
+process the download isn't always up to date.
+
+@node How to Use
+@chapter How to Use
+
+@section LibreJS in action
+
+After installing the add-on, you will see the LibreJS widget in the
+add-on bar at the top right of the browser window. After loading a
+page, left-click on the widget to view the deactivated JavaScript code
+from the page (both on page and external) and, if applicable, the
+scripts that were accepted.
+
+@section Script Blacklist/whitelist
+
+Scripts may be blacklisted or whitelisted through the pop-up menu box.
+
+Whitelisted scripts will always be accepted and blacklisted scripts
+will always get rejected.
+
+It is important to note that this feature recognizes which scripts are
+blacklisted and whitelisted based on hash. This means that even a slight
+difference in a script's code will cause it to be recognized as a
+seperate script.
+
+Sometimes, JavaScript will be dynamically generated so that it is
+different every time a website is loaded. These types of scripts cannot
+be whitelisted or blacklisted since they cannot be recognized.
+
+LibreJS has a default whitelist of scripts that are known to be free but
+may not use the format for declaring a license that it can understand.
+
+@section Complaint Feature
+
+It is very important to complain when a site has nonfree JavaScript
+code, especially if it won't work without that code. LibreJS makes it
+easy to complain by heuristically finding where to send the complaint.
+
+When nonfree/nontrivial code is detected in a page, LibreJS attempts to
+find a relevant contact link or email for the website you are
+visiting. In order to do so, it will attempt to visit a few links from
+the current page (for instance, a link labeled ``contact'' on the same
+domain as the current page, @dots{})
+
+LibreJS detects contact pages, email addresses that are likely to be
+owned by the maintainer of the site, Twitter and identi.ca links, and
+phone numbers.
+
+When you complain to the website for their nonfree nontrivial
+JavaScript, provide them with the link to the JavaScript Trap essay so
+that they can get more information on what the issue is and how they can
+solve it on their own site.
+
+LibreJS includes a default subject line and body for the complaint email,
+with a link to the JavaScript Trap essay. This can be configured in the
+LibreJS add-on preferences in your web browser.
+
+@section Options
+
+@table @dfn
+@item Whitelist
+
+LibreJS lets you whitelist domain names and subdomains to bypass the
+regular JavaScript check. This might be useful, for example, if you are
+running your own code in a local web server. In order to add a whitelisted
+domain or url, go to Tools >> Add-ons. Inside the add-on window, click on
+@dfn{Extensions}, and in the list, where you see LibreJS, click on the
+@dfn{Preferences} button. You will see an input field labeled @dfn{Whitelist}.
+
+In the field, enter comma-separated domain names. Do not enter the protocol.
+For instance to whitelist all the pages of @url{http://www.gnu.org} and
+@url{https://gnu.org}, enter @samp{gnu.org}. To allow all subdomains from
+gnu.org, enter: @samp{*.gnu.org}. This will match such sites as
+@url{http://savannah.gnu.org} and @url{http://audio-video.gnu.org}.
+
+@item Complaint email subject
+Configure the default subject used in complaint emails.
+
+@item Complaint email body
+Configure the default body used in complaint emails.
+@end table
+
+@node JavaScript Detection
+@chapter JavaScript Detection
+@cindex javascript
+
+LibreJS considers a very strict subset of JavaScript to be acceptable for use
+in non-free scripts. This is meant to maximimize compatibility with websites
+that haven't tried to be LibreJS compatible.
+
+We consider modification of the document non-trivial. There isn't
+much that javascript could do that we would consider trivial, for
+anything else a free software license would be required.
+
+The criterion is as follows:
+
+ For each function definition:
+@itemize @bullet
+ @item
+ It must call only primitives.
+ @item
+ The number of conditionals and loops must be at most 3.
+ @item
+ It does not declare an array more than 50 elements long.
+ @item
+ It must not call itself
+@end itemize
+
+For the rest of the script, outside of function definitions:
+@itemize @bullet
+ @item
+ It must call only primitives and functions defined above in the page.
+ @item
+ The number of conditionals and loops must be at most 3.
+@end itemize
+
+"function" means anything executable that gets a name, including methods.
+
+Allowed primitives exclude:
+ @itemize @bullet
+ @item
+ eval()
+ @item
+ ajax
+ @item
+ calling methods with the square bracket notation
+ @item
+ altering the dom
+ @item
+ most other items found as methods of the `.window` object.
+ @end itemize
+
+
+@node Free Licenses Detection
+@chapter Free Licenses Detection
+@cindex freelicenses
+
+The machine readable format for license declarations that LibreJS uses has changed
+in the most recent version. This was necessary in order to not break the asynchronous
+JS loading model that browsers use. Scripts are now evaluated independent of eachother
+and strictly as they arrive.
+
+@node Setting Your JavaScript Free
+@chapter Setting Your JavaScript Free
+
+The first step is releasing your JavaScript under a free license. If
+you are already using a free library, or you're not using any
+third-party libraries, it might only take a few minutes.
+
+On your website, take a look at your HTML source. You can identify
+distinct pieces of JavaScript that might be free and some other that are
+nonfree.
+
+This might be the case with an analytics tracker, social media
+widgets, and code that runs ads. Removing these pieces of code from your
+site is required to have the rest accepted as free. There are
+often alternatives to nonfree libraries or to third-party services:
+
+@itemize @bullet
+
+@item
+If you have used nonfree third-party code as the base to write your own
+code, try to find a free alternative.
+
+@item
+If you're using a third-party service such as an analytics service,
+replace it with a free alternative like Piwik.
+
+@item
+If you can't find free JavaScript that has already been developed,
+write it yourself! Who knows, your own solution might be the start of
+a brilliant project!
+@end itemize
+
+
+@section License tags
+
+LibreJS will allow non-trivial scripts to run as long as they use a
+free license.
+
+In order for the license of a script to be recognized by LibreJS, it
+must be declared using a machine-readable license format.
+
+This format is the same for both remote in-line scripts.
+

+@section Debugging
+
+To debug LibreJS, visit the special URL @code{about:debugging}. Click
+on `Enable add-on debugging` then `Load Temporary Add-on`. Navigate
+to LibreJS's unpacked source directory and select @file{manifest.json}.
+
+Lines 34 and 35 in @file{main_background.js} control the printing of
+@code{dbg_print()} statements. Make sure these are set to false in
+releases.
+
+@section Adding new whitelisted libraries
+
+The script index.js in @file{./hash_script} generates the default
+whitelist. Run it with the following command:
+
+@command{node index.js > output}
+
+Then, just copy the contents of the file "output" to the appropriate
+place in main_background.js.
+
+@section Releasing a new version
+
+Update the version number in manifest.json.
+
+Make sure debug statements are set to felse on lines 34/35 in

+Then, run the build script @file{build.sh}.
+
+@node Installation Requirements
+@appendix Installation Requirements
+
+
+@appendixsec Mozilla Browser
+
+You will need one of the many flavors of the Mozilla browser to use
+LibreJS. It can be installed on the following:
+
+GNU IceCat, Mozilla Firefox, Trisquel Abrowser, Debian Iceweasel.

+LibreJS works on these browsers starting from version 57. We recommend

+been tested on a GNU/Linux distribution, but it is compatible any
+operating system as long as you're using a compatible Mozilla browser.

+
+LibreJS intercepts HTTP responses and rewrites their contents after
+analyzing JavaScript within them. It does not remove script nodes and
+attributes from the page, but instead ``deactivates'' them by replacing
+their content with a commented notice.
+
+LibreJS detects the most common cases using the HTTP response method
+described above, but in less common edge cases, or when running code
+locally, LibreJS cannot detect JavaScript during the response stage.
