1 ================================================================
4 * This file attempts to describe the rules to use when hacking
7 * Don't put this file into the distribution. Don't mention it in the
11 ================================================================
14 * If you incorporate a change from somebody on the net:
15 First, if it is a large change, you must make sure they have signed the
16 appropriate paperwork.
17 Second, be sure to add their name and email address to THANKS
19 * If a change fixes a test, mention the test in the ChangeLog entry.
21 * If somebody reports a new bug, mention his name in the ChangeLog entry
22 and in the test case you write. Put him into THANKS.
24 * The correct response to most actual bugs is to write a new test case
25 which demonstrates the bug. Then fix the bug, re-run the test suite,
26 and check everything in.
28 * Some files in the automake package are not owned by automake. These
29 files should never be edited here. These files are COPYING, INSTALL,
30 ansi2knr.1, ansi2knr.c, config.guess config.sub, install-sh, mdate-sh,
31 missing, mkinstalldirs, texinfo.tex
33 * Changes other than bug fixes must be mentioned in NEWS
36 ================================================================
39 * We've adopted the convention that internal AC_SUBSTs should be
40 named with a leading `am__', and internally generated targets should
41 be named with a leading `am--'. This convention is very new
42 (as of Feb 7 2001) and so it isn't yet universally used. But all
43 new code should use it.
45 We used to use `_am_' as the prefix for an internal AC_SUBST.
46 However, it turns out that NEWS-OS 4.2R complains if a Makefile
47 variable begins with `_'. Yay for them. I changed the target
48 naming convention just to be safe.
50 ================================================================
53 * Always use $(...) and not ${...}
55 * Use `:', not `true'. Use `exit 1', not `false'.
57 * Use `##' comments liberally. Comment anything even remotely
60 * Never use basename or dirname. Instead use sed
62 * Do not use `cd' within back-quotes, use `$(am__cd)' instead.
63 Otherwise the directory name may be printed, depending on CDPATH.
65 * For install and uninstall rules, if a loop is required, it should be
66 silent. Then the body of the loop itself should print each
67 "important" command it runs. The printed commands should be preceded
71 ================================================================
72 = Editing automake.in and aclocal.in
74 * Indent using GNU style. For historical reasons, the perl code
75 contains portions indented using Larry Wall's style (perl-mode's
76 default), and other portions using the GNU style (cperl-mode's
77 default). Write new code using GNU style.
82 ================================================================
85 * To regenerate dependent files created by aclocal and automake,
86 use the `bootstrap' script. It uses the code from the source
87 tree, so the resulting files (aclocal.m4 and Makefile.in) should
88 be the same as you would get if you install this version of
89 automake and use it to generate those files.
91 * Dependent files aclocal.m4, configure and Makefile.in in all
92 directories should be up to date in the CVS repository, so that
93 the changes in them can be easily noticed and analyzed.
96 ================================================================
99 * Use "make check" and "make maintainer-check" liberally
101 * Make sure each test file is executable
104 ================================================================
107 * Fetch new versions of the files that are maintained by the FSF.
108 Commit. Unfortunately you need an FSF account to do this.
109 (You can also use `make fetch', but that is still woefully incomplete.)
111 * Update NEWS. For an alpha release, update README-alpha.
113 * Update the version number in configure.in.
114 (The idea is that every other alpha number will be a net release.
115 The repository will always have its own "odd" number so we can easily
116 distinguish net and repo versions.)
118 * Configure, build, and install.
120 * Run aclocal, automake, and autoconf.
124 * Run `make cvs-dist'
126 * Put new release on ftp site and send announcement to automake list.
127 If not an alpha, announcement must also go to FSF:
128 Put the files on a public ftp site and send a message to
130 Then send the announcement to info-gnu@gnu.org.
132 * Update version number in configure.in to next alpha number.
133 Re-run autoconf and commit.
