11   The GNU C++ Library follows an open development model. Active
12   contributors are assigned maintainer-ship responsibility, and given
13   write access to the source repository. First time contributors
14   should follow this procedure:

17           specification. Copies of the full ISO 14882 standard are
18           available on line via the ISO mirror site for committee
19           members. Non-members, or those who have not paid for the
20           privilege of sitting on the committee and sustained their
21           two meeting commitment for voting rights, may get a copy of
22           the standard from their respective national standards
23           organization. In the USA, this national standards
24           organization is
25           <a class="link" href="http://www.ansi.org" target="_top">ANSI</a>.

51       Small changes can be accepted without a copyright assignment form on
52       file. New code and additions to the library need completed copyright
53       assignment form on file at the FSF. Note: your employer may be required
54       to fill out appropriate disclaimer forms as well.
55     </p><p>
56       Historically, the libstdc++ assignment form added the following
57       question:
58     </p><p>
59       <span class="quote">“<span class="quote">
60         Which Belgian comic book character is better, Tintin or Asterix, and
61         why?
62       </span>”</span>
63     </p><p>
64       While not strictly necessary, humoring the maintainers and answering
65       this question would be appreciated.
66     </p><p>
67       For more information about getting a copyright assignment, please see
68       <a class="link" href="http://www.gnu.org/prep/maintain/html_node/Legal-Matters.html" target="_top">Legal
69         Matters</a>.

71       Please contact Benjamin Kosnik at
72       <code class="email">&lt;<a class="email" href="mailto:bkoz+assign@redhat.com">bkoz+assign@redhat.com</a>&gt;</code> if you are confused
73       about the assignment or have general licensing questions. When

81       Every patch must have several pieces of information before it can be
82       properly evaluated. Ideally (and to ensure the fastest possible
83       response from the maintainers) it would have all of these pieces:
84     </p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
85           A description of the bug and how your patch fixes this
86           bug. For new features a description of the feature and your
87           implementation.
88         </p></li><li class="listitem"><p>
89           A ChangeLog entry as plain text; see the various
90           ChangeLog files for format and content. If you are
91           using emacs as your editor, simply position the insertion
92           point at the beginning of your change and hit CX-4a to bring
93           up the appropriate ChangeLog entry. See--magic! Similar
94           functionality also exists for vi.
95         </p></li><li class="listitem"><p>
96           A testsuite submission or sample program that will
97           easily and simply show the existing error or test new
98           functionality.
99         </p></li><li class="listitem"><p>
100           The patch itself. If you are accessing the SVN
101           repository use <span class="command"><strong>svn update; svn diff NEW</strong></span>;
102           else, use <span class="command"><strong>diff -cp OLD NEW</strong></span> ... If your
103           version of diff does not support these options, then get the
104           latest version of GNU
105           diff. The <a class="link" href="http://gcc.gnu.org/wiki/SvnTricks" target="_top">SVN

109           When you have all these pieces, bundle them up in a
110           mail message and send it to libstdc++@gcc.gnu.org. All
111           patches and related discussion should be sent to the
