62 | =head2 Functions | |
63 | ||
64 | ExtUtils::Manifest exports no functions by default. The following are | |

71 | mkmanifest(); | |
72 | ||
73 | Writes all files in and below the current directory to your F<MANIFEST>. | |
74 | It works similar to | |
75 | ||
76 | find . > MANIFEST | |
77 | ||
78 | All files that match any regular expression in a file F<MANIFEST.SKIP> | |
79 | (if it exists) are ignored. | |
80 | ||
81 | Any existing F<MANIFEST> file will be saved as F<MANIFEST.bak>. Lines | |
82 | from the old F<MANIFEST> file is preserved, including any comments | |
83 | that are found in the existing F<MANIFEST> file in the new one. | |

588 | =head2 MANIFEST | |
589 | ||
590 | A list of files in the distribution, one file per line. The MANIFEST | |
591 | always uses Unix filepath conventions even if you're not on Unix. This | |
592 | means F<foo/bar> style not F<foo\bar>. | |
593 | ||
594 | Anything between white space and an end of line within a C<MANIFEST> | |
595 | file is considered to be a comment. Any line beginning with # is also | |
596 | a comment. | |
597 | ||
598 | # this a comment | |
599 | some/file | |
600 | some/other/file comment about some/file | |
601 | ||
602 | ||
603 | =head2 MANIFEST.SKIP | |
604 | ||
605 | The file MANIFEST.SKIP may contain regular expressions of files that | |
606 | should be ignored by mkmanifest() and filecheck(). The regular | |
607 | expressions should appear one on each line. Blank lines and lines | |
608 | which start with C<#> are skipped. Use C<\#> if you need a regular | |
609 | expression to start with a C<#>. | |
610 | ||
611 | For example: | |
612 | ||
613 | # Version control files and dirs. | |
614 | \bRCS\b | |
615 | \bCVS\b | |
616 | ,v$ | |
617 | \B\.svn\b | |
618 | ||
619 | # Makemaker generated files and dirs. | |
620 | ^MANIFEST\. | |
621 | ^Makefile$ | |
622 | ^blib/ | |
623 | ^MakeMaker-\d | |
624 | ||
625 | # Temp, old and emacs backup files. | |
626 | ~$ | |
627 | \.old$ | |
628 | ^#.*#$ | |
629 | ^\.# | |
630 | ||
631 | If no MANIFEST.SKIP file is found, a default set of skips will be | |
632 | used, similar to the example above. If you want nothing skipped, | |
633 | simply make an empty MANIFEST.SKIP file. | |
634 | ||
635 | ||
636 | =head2 EXPORT_OK | |
637 | ||
638 | C<&mkmanifest>, C<&manicheck>, C<&filecheck>, C<&fullcheck>, | |
639 | C<&maniread>, and C<&manicopy> are exportable. | |
640 | ||
641 | =head2 GLOBAL VARIABLES | |
642 | ||
643 | C<$ExtUtils::Manifest::MANIFEST> defaults to C<MANIFEST>. Changing it | |
644 | results in both a different C<MANIFEST> and a different | |
645 | C<MANIFEST.SKIP> file. This is useful if you want to maintain | |
646 | different distributions for different audiences (say a user version | |
647 | and a developer version including RCS). | |
648 | ||
649 | C<$ExtUtils::Manifest::Quiet> defaults to 0. If set to a true value, | |
650 | all functions act silently. | |
651 | ||
652 | C<$ExtUtils::Manifest::Debug> defaults to 0. If set to a true value, | |
653 | or if PERL_MM_MANIFEST_DEBUG is true, debugging output will be | |
654 | produced. | |
655 | ||
656 | =head1 DIAGNOSTICS | |
657 | ||
658 | All diagnostic output is sent to C<STDERR>. | |
659 | ||
660 | =over 4 | |
661 | ||
662 | =item C<Not in MANIFEST:> I<file> | |
663 | ||

665 | ||
666 | =item C<Skipping> I<file> | |
667 | ||
668 | is reported if a file is skipped due to an entry in C<MANIFEST.SKIP>. | |
669 | ||
670 | =item C<No such file:> I<file> | |
671 | ||
672 | is reported if a file mentioned in a C<MANIFEST> file does not | |
673 | exist. | |
674 | ||
675 | =item C<MANIFEST:> I<$!> | |
676 | ||
677 | is reported if C<MANIFEST> could not be opened. | |
678 | ||
679 | =item C<Added to MANIFEST:> I<file> | |
680 | ||
681 | is reported by mkmanifest() if $Verbose is set and a file is added | |
682 | to MANIFEST. $Verbose is set to 1 by default. | |
