7 | =head1 NAME |
8 | ||
9 | Porting/pod_lib.pl - functions for building and installing POD | |
10 | ||
11 | =head1 SYNOPSIS | |
12 | ||
13 | require './Porting/pod_lib.pl'; | |
14 | ||
15 | =cut | |
16 | ||
17 | =head1 DESCRIPTION | |
18 | ||
19 | This program, when C<require>d into other programs in the Perl 5 core | |
20 | distribution, provides functions useful during building and, secondarily, | |
21 | testing. | |
22 | ||
23 | As of this writing, the functions in this program are used in these other | |
24 | programs: | |
25 | ||
26 | installman | |
27 | installperl | |
28 | pod/buildtoc | |
29 | pod/perl.pod | |
30 | Porting/new-perldelta.pl | |
31 | Porting/pod_rules.pl | |
32 | ||
33 | Note: Since these functions are used during the Perl build process, they must | |
34 | work with F<miniperl>. That necessarily implies that these functions must not | |
35 | rely on XS modules, either directly or indirectly (e.g., C<autodie>). | |

42 | ||
43 | =item * Purpose | |
44 | ||
45 | Exit from a process with an error code and a message. | |

210 | ||
211 | Read a file from disk, pass the contents to the callback, and either update | |

213 | version on disk is up to date. C<die>s if the file contains any C<NUL> bytes. | |

229 | =item * Test number | |
230 | ||
231 | If defined, generate TAP output to C<STDOUT>. If defined and false, generate | |
232 | an unnumbered test. Otherwise this is the test number in the I<ok> line. | |
