61 | |
62 | =head2 Functions |
63 | |
64 | ExtUtils::Manifest exports no functions by default. The following are |
65 | exported on request |

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 |
79dd614e |
589 | |
5dca256e |
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 | |
479d2113 |
594 | Anything between white space and an end of line within a C<MANIFEST> |
5dca256e |
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 |

603 | =head2 MANIFEST.SKIP |
79dd614e |
604 | |
605 | The file MANIFEST.SKIP may contain regular expressions of files that |
606 | should be ignored by mkmanifest() and filecheck(). The regular |
15a074ca |
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 |
5dca256e |
609 | expression to start with a C<#>. |
610 | |
611 | For example: |
79dd614e |
612 | |
0b9c804f |
613 | # Version control files and dirs. |
79dd614e |
614 | \bRCS\b |
0b9c804f |
615 | \bCVS\b |
616 | ,v$ |
479d2113 |
617 | \B\.svn\b |
0b9c804f |
618 | |
619 | # Makemaker generated files and dirs. |
79dd614e |
620 | ^MANIFEST\. |
621 | ^Makefile$ |
79dd614e |
622 | ^blib/ |
623 | ^MakeMaker-\d |
624 | |
0b9c804f |
625 | # Temp, old and emacs backup files. |
626 | ~$ |
627 | \.old$ |
628 | ^#.*#$ |
cfcce72b |
629 | ^\.# |
0b9c804f |
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. |

641 | =head2 GLOBAL VARIABLES |
79dd614e |
642 | |
643 | C<$ExtUtils::Manifest::MANIFEST> defaults to C<MANIFEST>. Changing it |
644 | results in both a different C<MANIFEST> and a different |
645 | C<MANIFEST.SKIP> file. This is useful if you want to maintain |
646 | different distributions for different audiences (say a user version |
647 | and a developer version including RCS). |
648 | |
81ff29e3 |
649 | C<$ExtUtils::Manifest::Quiet> defaults to 0. If set to a true value, |
79dd614e |
650 | all functions act silently. |
651 | |
0b9c804f |
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 | |
79dd614e |
656 | =head1 DIAGNOSTICS |
