37 | =head1 NAME | |
38 | ||
39 | ExtUtils::Manifest - utilities to write and check a MANIFEST file | |
40 | ||
41 | =head1 SYNOPSIS | |
42 | ||
43 | use ExtUtils::Manifest qw(...funcs to import...); | |
44 | ||
45 | mkmanifest(); | |

61 | =head1 DESCRIPTION | |
62 | ||
63 | =head2 Functions | |
64 | ||
65 | ExtUtils::Manifest exports no functions by default. The following are | |
66 | exported on request | |
67 | ||
68 | =over 4 | |
69 | ||
70 | =item mkmanifest | |
71 | ||
72 | mkmanifest(); | |
73 | ||
74 | Writes all files in and below the current directory to your F<MANIFEST>. | |
6dbcfe36 | 75 | It works similar to the result of the Unix command |
479d2113 MS |
76 | |
77 | find . > MANIFEST | |
78 | ||
79 | All files that match any regular expression in a file F<MANIFEST.SKIP> | |
80 | (if it exists) are ignored. | |
81 | ||
6dbcfe36 | 82 | Any existing F<MANIFEST> file will be saved as F<MANIFEST.bak>. |

700 | A list of files in the distribution, one file per line. The MANIFEST |

79dd614e | 717 | |

15a074ca A |
720 | expressions should appear one on each line. Blank lines and lines |
721 | which start with C<#> are skipped. Use C<\#> if you need a regular | |
5dca256e RGS |
722 | expression to start with a C<#>. |
723 | ||
724 | For example: | |
79dd614e | 725 | |

747 | ||
1c14aae0 RGS |
748 | In one's own MANIFEST.SKIP file, certain directives |
749 | can be used to include the contents of other MANIFEST.SKIP | |
750 | files. At present two such directives are recognized. | |
751 | ||
752 | =over 4 | |

759 | ||
760 | This inserts the contents of the specified external file | |
761 | ||
762 | =back | |
763 | ||
764 | The included contents will be inserted into the MANIFEST.SKIP | |
765 | file in between I<#!start included /path/to/manifest.skip> | |
766 | and I<#!end included /path/to/manifest.skip> markers. | |
