-
-ExtUtils::Manifest - utilities to write and check a MANIFEST file
-
-=head1 SYNOPSIS
-
-C<require ExtUtils::Manifest;>
-
-C<ExtUtils::Manifest::mkmanifest;>
-
-C<ExtUtils::Manifest::manicheck;>
-
-C<ExtUtils::Manifest::filecheck;>
-
-C<ExtUtils::Manifest::fullcheck;>
-
-C<ExtUtils::Manifest::maniread($file);>
-
-C<ExtUtils::Manifest::manicopy($read,$target);>
-
-=head1 DESCRIPTION
-
-Mkmanifest() writes all files in and below the current directory to a
-file named C<MANIFEST> in the current directory. It works similar to
-
- find . -print
-
-but in doing so checks each line in an existing C<MANIFEST> file and
-includes any comments that are found in the existing C<MANIFEST> file
-in the new one. Anything between white space and an end of line within
-a C<MANIFEST> file is considered to be a comment. Filenames and
-comments are seperated by one or more TAB characters in the
-output. All files that match any regular expression in a file
-C<MANIFEST.SKIP> (if such a file exists) are ignored.
-
-Manicheck() checks if all the files within a C<MANIFEST> in the current
-directory really do exist.
-
-Filecheck() finds files below the current directory that are not
-mentioned in the C<MANIFEST> file. An optional file C<MANIFEST.SKIP>
-will be consulted. Any file matching a regular expression in such a
-file will not be reported as missing in the C<MANIFEST> file.
-
-Fullcheck() does both a manicheck() and a filecheck().
-
-Maniread($file) reads a named C<MANIFEST> file (defaults to
-C<MANIFEST> in the current directory) and returns a HASH reference
-with files being the keys and comments being the values of the HASH.
-
-I<Manicopy($read,$target)> copies the files that are the keys in the
-HASH I<%$read> to the named target directory. The HASH reference
-I<$read> is typically returned by the maniread() function. This
-function is useful for producing a directory tree identical to the
-intended distribution tree.
-
-=head1 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. A typical example:
-
- \bRCS\b
- ^MANIFEST\.
- ^Makefile$
- ~$
- \.html$
- \.old$
- ^blib/
- ^MakeMaker-\d
-
-=head1 EXPORT_OK
-
-C<&mkmanifest>, C<&manicheck>, C<&filecheck>, C<&fullcheck>,
-C<&maniread>, and C<&manicopy> are exportable.
-
-=head1 DIAGNOSTICS
-
-All diagnostic output is sent to C<STDERR>.
-
-=over
-
-=item C<Not in MANIFEST:> I<file>
-is reported if a file is found, that is missing in the C<MANIFEST>
-file which is excluded by a regular expression in the file
-C<MANIFEST.SKIP>.
-
-=item C<No such file:> I<file>
-is reported if a file mentioned in a C<MANIFEST> file does not
-exist.
-
-=item C<MANIFEST:> I<$!>
-is reported if C<MANIFEST> could not be opened.
-
-=item C<Added to MANIFEST:> I<file>
-is reported by mkmanifest() if $Verbose is set and a file is added
-to MANIFEST. $Verbose is set to 1 by default.

+
+=head1 DESCRIPTION
+
+Mkmanifest() writes all files in and below the current directory to a
+file named in the global variable $ExtUtils::Manifest::MANIFEST (which
+defaults to C<MANIFEST>) in the current directory. It works similar to
+
+ find . -print
+
+but in doing so checks each line in an existing C<MANIFEST> file and
+includes any comments that are found in the existing C<MANIFEST> file
+in the new one. Anything between white space and an end of line within
+a C<MANIFEST> file is considered to be a comment. Filenames and
+comments are seperated by one or more TAB characters in the
+output. All files that match any regular expression in a file
+C<MANIFEST.SKIP> (if such a file exists) are ignored.
+
+Manicheck() checks if all the files within a C<MANIFEST> in the
+current directory really do exist. It only reports discrepancies and
+exits silently if MANIFEST and the tree below the current directory
+are in sync.
+
+Filecheck() finds files below the current directory that are not
+mentioned in the C<MANIFEST> file. An optional file C<MANIFEST.SKIP>
+will be consulted. Any file matching a regular expression in such a
+file will not be reported as missing in the C<MANIFEST> file.
+
+Fullcheck() does both a manicheck() and a filecheck().
+
+Skipcheck() lists all the files that are skipped due to your
+C<MANIFEST.SKIP> file.
+
+Manifind() retruns a hash reference. The keys of the hash are the
+files found below the current directory.
+
+Maniread($file) reads a named C<MANIFEST> file (defaults to
+C<MANIFEST> in the current directory) and returns a HASH reference
+with files being the keys and comments being the values of the HASH.
+Blank lines and lines which start with C<#> in the C<MANIFEST> file
+are discarded.
+
+I<Manicopy($read,$target,$how)> copies the files that are the keys in
+the HASH I<%$read> to the named target directory. The HASH reference
+I<$read> is typically returned by the maniread() function. This
+function is useful for producing a directory tree identical to the
+intended distribution tree. The third parameter $how can be used to
+specify a different methods of "copying". Valid values are C<cp>,
+which actually copies the files, C<ln> which creates hard links, and
+C<best> which mostly links the files but copies any symbolic link to
+make a tree without any symbolic link. Best is the default.
+
+=head1 MANIFEST.SKIP
+
+The file MANIFEST.SKIP may contain regular expressions of files that
+should be ignored by mkmanifest() and filecheck(). The regular
+expressions should appear one on each line. Blank lines and lines
+which start with C<#> are skipped. Use C<\#> if you need a regular
+expression to start with a sharp character. A typical example:
+
+ \bRCS\b
+ ^MANIFEST\.
+ ^Makefile$
+ ~$
+ \.html$
+ \.old$
+ ^blib/
+ ^MakeMaker-\d
+
+=head1 EXPORT_OK
+
+C<&mkmanifest>, C<&manicheck>, C<&filecheck>, C<&fullcheck>,
+C<&maniread>, and C<&manicopy> are exportable.
+
+=head1 GLOBAL VARIABLES
+
+C<$ExtUtils::Manifest::MANIFEST> defaults to C<MANIFEST>. Changing it
+results in both a different C<MANIFEST> and a different
+C<MANIFEST.SKIP> file. This is useful if you want to maintain
+different distributions for different audiences (say a user version
+and a developer version including RCS).
+
+C<$ExtUtils::Manifest::Quiet> defaults to 0. If set to a true value,
+all functions act silently.
+
+=head1 DIAGNOSTICS
+
+All diagnostic output is sent to C<STDERR>.
+
+=over
+
+=item C<Not in MANIFEST:> I<file>
+
+is reported if a file is found, that is missing in the C<MANIFEST>
+file which is excluded by a regular expression in the file
+C<MANIFEST.SKIP>.
+
+=item C<No such file:> I<file>
+
+is reported if a file mentioned in a C<MANIFEST> file does not
+exist.
+
+=item C<MANIFEST:> I<$!>
+
+is reported if C<MANIFEST> could not be opened.
+
+=item C<Added to MANIFEST:> I<file>
+
+is reported by mkmanifest() if $Verbose is set and a file is added
+to MANIFEST. $Verbose is set to 1 by default.
