3 README.pod - README for the F<Porting/> directory in the Perl 5 core distribution.
7 =head2 F<acknowledgements.pl>
9 Generates the text which goes in the Acknowledgements section in
10 a perldelta. You pass in the previous version and it guesses the next
11 version, fetches information from the repository and outputs the
14 =head2 F<add-package.pl>
16 Program to prepare dual-life distributions for insertion into the Perl 5
17 F<lib/> and F<t/> directories. Now thought to be largely superseded.
19 =head2 F<add-pod-file>
21 Program to facilitate addition of new F<.pod> files to F<pod/>.
25 Do performance analysis on the code snippets in F<t/perf/benchmarks>.

29 Use C<git bisect> to pinpoint changes.
31 =head2 F<bump-perl-version>

34 number in various files within the perl source.
36 =head2 F<checkansi.pl>
38 Check source code for ANSI-C violations.
40 =head2 F<checkAUTHORS.pl>
42 Used by F<t/porting/authors.t> to ensure the F<AUTHORS> list is up to
43 date. See also L<< /"F<updateAUTHORS.pl>" >> for a way to automatically
44 fix issues found by this tool.
46 =head2 F<checkcfguse.pl>
48 Check where the symbols defined in the various F<config.sh>-clones
49 are being used. VMS is probably not handled properly here.
51 =head2 F<checkcfgvar.pl>
53 Check that the various F<config.sh>-clones have (at least) all the same
54 symbols as the top-level F<config_h.SH> so that the (potentially) needed
55 symbols are not lagging after how F<Configure> thinks the world is laid out.
56 VMS is probably not handled properly here, due to their own rather elaborate
59 =head2 F<check-cpan-pollution>
61 Scans the commit logs for commits that are potentially, illegitimately
62 touching modules that are primarily maintained outside of the perl core. Also
63 checks for commits that span multiple distributions in F<cpan/> or F<dist/>.
64 Makes sure that updated CPAN distributions also update
65 F<Porting/Maintainers.pl>, but otherwise ignores changes to that file (and
68 =head2 F<checkpodencoding.pl>
70 Check if POD files contain non-ASCII without specifying
71 encoding. Run it as: C<perl Porting/checkpodencoding.pl>.
75 Checks that all the URLs in the Perl source are valid.
77 =head2 F<checkVERSION.pl>
79 Used by F<t/porting/cmp_version.t> to ensure changed modules have had their
82 =head2 F<cmpVERSION.pl>
84 Compare the current Perl source tree and a given tag for modules that have
85 identical version numbers but different contents.
89 This file is a sample F<config.h> file. If you are unable to successfully run
90 F<Configure>, copy this file to F<config.h> and edit it to suit your system.
94 Used when importing changes from F<metaconfig>. This script reorders
95 F<config_h.SH> after metaconfig.
99 This file is a sample F<config.sh> file. F<config.sh> is normally
100 produced by running the F<Configure> script. It holds all the definitions
101 figured out by F<Configure>. If you are unable to successfully run
102 F<Configure> on your system, copy this sample file to F<config.sh>
103 at the top of the perl source tree and edit it to suit your system.
104 Then propagate those values by running C<Configure -S>. This sample
105 file is normally updated each time F<Configure> is updated.
107 =head2 F<core-cpan-diff>

184 committish (the SHA1 checksum of a commit, a number made of 40 hexadecimal
185 digits which acts the internal unique identifier for this commit
186 (lilypond.org). Related file: F<make_dot_patch.pl>
190 This file is built by F<metaconfig>. This file contains a description of all
191 the shell variables whose value is determined by the Configure script.

240 =head2 F<make-rmg-checklist>
242 This script creates a release checklist as a simple HTML document.

316 This file. An exhaustive list of the contents of the F<Porting/>
317 directory along with a description of each file.
318 The test F<t/porting/readme.t> ensures that this lists every file
319 and that every file is listed.

379 any previous attempts.
