The MANIFEST always uses Unix filepath conventions even if you're not on Unix. This means F style not F. Anything between white space and an end of line within a C file is considered to be a comment. Any line beginning with # is also a comment. Beginning with ExtUtils::Manifest 1.52, a filename may contain whitespace characters if it is enclosed in single quotes; single quotes or backslashes in that filename must be backslash-escaped. # this a comment some/file some/other/file comment about some/file 'some/third file' comment =head2 MANIFEST.SKIP The file MANIFEST.SKIP may contain regular expressions of files that should be ignored by mkmanifest() and filecheck(). The regular expressions should appear one on each line. Blank lines and lines which start with C<#> are skipped. Use C<\#> if you need a regular expression to start with a C<#>. For example: # Version control files and dirs. \bRCS\b \bCVS\b ,v$ \B\.svn\b # Makemaker generated files and dirs. ^MANIFEST\. ^Makefile$ ^blib/ ^MakeMaker-\d # Temp, old and emacs backup files. ~$ \.old$ ^#.*#$ ^\.# If no MANIFEST.SKIP file is found, a default set of skips will be used, similar to the example above. If you want nothing skipped, simply make an empty MANIFEST.SKIP file. In one's own MANIFEST.SKIP file, certain directives can be used to include the contents of other MANIFEST.SKIP files. At present two such directives are recognized. =over 4 =item #!include_default This inserts the contents of the default MANIFEST.SKIP file =item #!include /Path/to/another/manifest.skip This inserts the contents of the specified external file =back The included contents will be inserted into the MANIFEST.SKIP file in between I<#!start included /path/to/manifest.skip> and I<#!end included /path/to/manifest.skip> markers.
