+                        Contributing to Emacs
+
+Emacs is a collaborative project and we encourage contributions from
+anyone and everyone.  If you want to contribute in the way that will
+help us most, we recommend (1) fixing reported bugs and (2)
+implementing the feature ideas in etc/TODO.  However, if you think of
+new features to add, please suggest them too -- we might like your
+idea.  Porting to new platforms is also useful, when there is a new
+platform, but that is not common nowadays.
+
+For documentation on how to develop Emacs changes, refer to the Emacs
+Manual and the Emacs Lisp Reference Manual (both included in the Emacs
+distribution).  The web pages in http://www.gnu.org/software/emacs
+contain additional information.
+
+You may also want to submit your change so that can be considered for
+inclusion in a future version of Emacs (see below).
+
+If you don't feel up to hacking Emacs, there are many other ways to
+help.  You can answer questions on the mailing lists, write
+documentation, find and report bugs, check if existing bug reports
+are fixed in newer versions of Emacs, contribute to the Emacs web
+pages, or develop a package that works with Emacs.
+
+Here are some style and legal conventions for contributors to Emacs:
+
+
+* Coding Standards
+
+Contributed code should follow the GNU Coding Standards.
+
+If it doesn't, we'll need to find someone to fix the code before we
+can use it.
+
+Emacs has certain additional style and coding conventions.
+
+Ref: http://www.gnu.org/prep/standards/
+Ref: GNU Coding Standards Info Manual
+Ref: The "Tips" Appendix in the Emacs Lisp Reference.
+
+
+* Copyright Assignment
+
+The FSF (Free Software Foundation) is the copyright holder for GNU Emacs.
+The FSF is a nonprofit with a worldwide mission to promote computer
+user freedom and to defend the rights of all free software users.
+For general information, see the website http://www.fsf.org/ .
+
+Generally speaking, for non-trivial contributions to GNU Emacs we
+require that the copyright be assigned to the FSF.  For the reasons
+behind this, see: http://www.gnu.org/licenses/why-assign.html .
+
+Copyright assignment is a simple process.  Residents of some countries
+can do it entirely electronically.  We can help you get started, and
+answer any questions you may have (or point you to the people with the
+answers), at the emacs-devel@gnu.org mailing list.
+
+(Please note: general discussion about why some GNU projects ask
+for a copyright assignment is off-topic for emacs-devel.
+See gnu-misc-discuss instead.)
+
+A copyright disclaimer is also a possibility, but we prefer an assignment.
+Note that the disclaimer, like an assignment, involves you sending
+signed paperwork to the FSF (simply saying "this is in the public domain"
+is not enough).  Also, a disclaimer cannot be applied to future work, it
+has to be repeated each time you want to send something new.
+
+We can accept small changes (roughly, fewer than 15 lines) without
+an assignment.  This is a cumulative limit (e.g. three separate 5 line
+patches) over all your contributions.
+
+* Getting the Source Code
+
+The latest version of the Emacs source code can be downloaded from the
+Savannah web site.  It is important to write your patch based on the
+latest version.  If you start from an older version, your patch may be
+outdated (so that maintainers will have a hard time applying it), or
+changes in Emacs may have made your patch unnecessary.
+
+After you have downloaded the repository source, you should read the file
+INSTALL.REPO for build instructions (they differ to some extent from a
+normal build).
+
+Ref: http://savannah.gnu.org/projects/emacs
+
+
+* Submitting Patches
+
+Every patch must have several pieces of information before we
+can properly evaluate it.
+
+When you have all these pieces, bundle them up in a mail message and
+send it to the developers.  Sending it to bug-gnu-emacs@gnu.org
+(which is the bug/feature list) is recommended, because that list
+is coupled to a tracking system that makes it easier to locate patches.
+If your patch is not complete and you think it needs more discussion,
+you might want to send it to emacs-devel@gnu.org instead.  If you
+revise your patch, send it as a followup to the initial topic.
+
+** Description
+
+For bug fixes, a description of the bug and how your patch fixes it.
+
+For new features, a description of the feature and your implementation.
+
+** ChangeLog
+
+A ChangeLog entry as plaintext (separate from the patch).
+
+See the existing ChangeLog files for format and content.  Note that,
+unlike some other projects, we do require ChangeLogs also for
+documentation, i.e. Texinfo files.
+
+Ref: "Change Log Concepts" node of the GNU Coding Standards Info
+Manual, for how to write good log entries.
+
+When using git, commit messages should use ChangeLog format, with a
+single short line explaining the change, then an empty line, then
+unindented ChangeLog entries.  (Essentially, a commit message should
+be a duplicate of what the patch adds to the ChangeLog files.  We are
+planning to automate this better, to avoid the duplication.)
+
+** The patch itself.
+
+If you are accessing the Emacs repository, make sure your copy is
+up-to-date (e.g. with 'git pull').  You can commit your changes
+to a private branch and generate a patch from the master version
+by using
+        git format-patch master
+Or you can leave your changes uncommitted and use
+        git diff
+With no repository, you can use
+        diff -u OLD NEW
+
+** Mail format.
+
+We prefer to get the patches as plain text, either inline (be careful
+your mail client does not change line breaks) or as MIME attachments.
+
+** Please reread your patch before submitting it.
+
+** Do not mix changes.
+
+If you send several unrelated changes together, we will ask you to
+separate them so we can consider each of the changes by itself.
+
+** Do not make formatting changes.
+
+Making cosmetic formatting changes (indentation, etc) makes it harder
+to see what you have really changed.
+
+
+* Coding style and conventions.
+
+** Mandatory reading:
+
+The "Tips and Conventions" Appendix of the Emacs Lisp Reference.
+
+** Avoid using `defadvice' or `eval-after-load' for Lisp code to be
+included in Emacs.
+
+** Remove all trailing whitespace in all source and text files.
+
+** Use ?\s instead of ?  in Lisp code for a space character.
+
+
+* Supplemental information for Emacs Developers.
+
+** Write access to the Emacs repository.
+
+Once you become a frequent contributor to Emacs, we can consider
+giving you write access to the version-control repository.
+
+
+** Emacs Mailing lists.
+
+Discussion about Emacs development takes place on emacs-devel@gnu.org.
+
+Bug reports and fixes, feature requests and implementations should be
+sent to bug-gnu-emacs@gnu.org, the bug/feature list.  This is coupled
+to the tracker at http://debbugs.gnu.org .
+
+You can subscribe to the mailing lists, or see the list archives,
+by following links from http://savannah.gnu.org/mail/?group=emacs .
+
+** Document your changes.
+
+Any change that matters to end-users should have a NEWS entry.
+
+Think about whether your change requires updating the documentation
+(both manuals and doc-strings).  If you know it does not, mark the NEWS
+entry with "---".  If you know that *all* the necessary documentation
+updates have been made, mark the entry with "+++". Otherwise do not mark it.
+
+** Understanding Emacs Internals.
+
+The best way to understand Emacs Internals is to read the code,
+but the nodes "Tips" and "GNU Emacs Internals" in the Appendix
+of the Emacs Lisp Reference Manual may also help.
+
+The file etc/DEBUG describes how to debug Emacs bugs.

+
+/* Usage suggestions:
+
+   Programs that use <stdbool.h> should be aware of some limitations
+   and standards compliance issues.
+
+   Standards compliance:
+
+       - <stdbool.h> must be #included before 'bool', 'false', 'true'
+         can be used.
+
+       - You cannot assume that sizeof (bool) == 1.
+
+       - Programs should not undefine the macros bool, true, and false,
+         as C99 lists that as an "obsolescent feature".
+
+   Limitations of this substitute, when used in a C89 environment:
+
+       - <stdbool.h> must be #included before the '_Bool' type can be used.
+
+       - You cannot assume that _Bool is a typedef; it might be a macro.
+
+       - Bit-fields of type 'bool' are not supported.  Portable code
+         should use 'unsigned int foo : 1;' rather than 'bool foo : 1;'.
+
+       - In C99, casts and automatic conversions to '_Bool' or 'bool' are
+         performed in such a way that every nonzero value gets converted
+         to 'true', and zero gets converted to 'false'.  This doesn't work
+         with this substitute.  With this substitute, only the values 0 and 1
+         give the expected result when converted to _Bool' or 'bool'.
+
+       - C99 allows the use of (_Bool)0.0 in constant expressions, but
+         this substitute cannot always provide this property.
+
+   Also, it is suggested that programs use 'bool' rather than '_Bool';
+   this isn't required, but 'bool' is more common.  */

+With a prefix argument ARG, enable Capitalized Words mode if ARG

+enable the mode if ARG is omitted or nil.
+
+Capitalized Words mode is a buffer-local minor mode.  When
+enabled, a word boundary occurs immediately before an uppercase
+letter in a symbol.  This is in addition to all the normal
+boundaries given by the syntax and category tables.  There is no
+restriction to ASCII.
+
+E.g. the beginning of words in the following identifier are as marked:

+
+Note that these word boundaries only apply for word motion and
+marking commands such as \\[forward-word].  This mode does not affect word
+boundaries found by regexp matching (`\\>', `\\w' &c).
+
+This style of identifiers is common in environments like Java ones,
+where underscores aren't trendy enough.  Capitalization rules are
+sometimes part of the language, e.g. Haskell, which may thus encourage
+such a style.  It is appropriate to add `capitalized-words-mode' to
+the mode hook for programming language modes in which you encounter
+variables like this, e.g. `java-mode-hook'.  It's unlikely to cause
+trouble if such identifiers aren't used.
+
+See also `glasses-mode' and `studlify-word'.
