.Sh "Functions"
.IX Subsection "Functions"
ExtUtils::Manifest exports no functions by default.  The following are
exported on request
.IP "mkmanifest" 4
.IX Item "mkmanifest"
.Vb 1
\&    mkmanifest();
.Ve
.Sp
Writes all files in and below the current directory to your \fI\s-1MANIFEST\s0\fR.
It works similar to
.Sp
.Vb 1
\&    find . > MANIFEST
.Ve
.Sp
All files that match any regular expression in a file \fI\s-1MANIFEST\s0.SKIP\fR
(if it exists) are ignored.
.Sp
Any existing \fI\s-1MANIFEST\s0\fR file will be saved as \fI\s-1MANIFEST\s0.bak\fR.  Lines
from the old \fI\s-1MANIFEST\s0\fR file is preserved, including any comments
that are found in the existing \fI\s-1MANIFEST\s0\fR file in the new one.
.IP "manifind" 4
.IX Item "manifind"
.Vb 1
\&    my $found = manifind();
.Ve
.Sp
returns a hash reference. The keys of the hash are the files found
below the current directory.
.IP "manicheck" 4
.IX Item "manicheck"
.Vb 1
\&    my @missing_files = manicheck();
.Ve
.Sp
checks if all the files within a \f(CW\*(C`MANIFEST\*(C'\fR in the current directory
really do exist. If \f(CW\*(C`MANIFEST\*(C'\fR and the tree below the current
directory are in sync it silently returns an empty list.
Otherwise it returns a list of files which are listed in the
\&\f(CW\*(C`MANIFEST\*(C'\fR but missing from the directory, and by default also
outputs these names to \s-1STDERR\s0.
.IP "filecheck" 4
.IX Item "filecheck"
.Vb 1
\&    my @extra_files = filecheck();
.Ve
.Sp
finds files below the current directory that are not mentioned in the
\&\f(CW\*(C`MANIFEST\*(C'\fR file. An optional file \f(CW\*(C`MANIFEST.SKIP\*(C'\fR will be
consulted. Any file matching a regular expression in such a file will
not be reported as missing in the \f(CW\*(C`MANIFEST\*(C'\fR file. The list of any
extraneous files found is returned, and by default also reported to
\&\s-1STDERR\s0.
.IP "fullcheck" 4
.IX Item "fullcheck"
.Vb 1
\&    my($missing, $extra) = fullcheck();
.Ve
.Sp
does both a \fImanicheck()\fR and a \fIfilecheck()\fR, returning then as two array
refs.
.IP "skipcheck" 4
.IX Item "skipcheck"
.Vb 1
\&    my @skipped = skipcheck();
.Ve
.Sp
lists all the files that are skipped due to your \f(CW\*(C`MANIFEST.SKIP\*(C'\fR
file.
.IP "maniread" 4
.IX Item "maniread"
.Vb 2
\&    my $manifest = maniread();
\&    my $manifest = maniread($manifest_file);
.Ve
.Sp
reads a named \f(CW\*(C`MANIFEST\*(C'\fR file (defaults to \f(CW\*(C`MANIFEST\*(C'\fR in the current
directory) and returns a \s-1HASH\s0 reference with files being the keys and
comments being the values of the \s-1HASH\s0.  Blank lines and lines which
start with \f(CW\*(C`#\*(C'\fR in the \f(CW\*(C`MANIFEST\*(C'\fR file are discarded.
.IP "manicopy" 4
.IX Item "manicopy"
.Vb 2
\&    manicopy(\e%src, $dest_dir);
\&    manicopy(\e%src, $dest_dir, $how);
.Ve
.Sp
Copies the files that are the keys in \f(CW%src\fR to the \f(CW$dest_dir\fR.  \f(CW%src\fR is
typically returned by the \fImaniread()\fR function.
.Sp
.Vb 1
\&    manicopy( maniread(), $dest_dir );
.Ve
.Sp
This function is useful for producing a directory tree identical to the 
intended distribution tree.
.Sp
\&\f(CW$how\fR can be used to specify a different methods of \*(L"copying\*(R".  Valid
values are \f(CW\*(C`cp\*(C'\fR, which actually copies the files, \f(CW\*(C`ln\*(C'\fR which creates
hard links, and \f(CW\*(C`best\*(C'\fR which mostly links the files but copies any
symbolic link to make a tree without any symbolic link.  \f(CW\*(C`cp\*(C'\fR is the 
default.
.IP "maniadd" 4
.IX Item "maniadd"
.Vb 1
\&  maniadd({ $file => $comment, ...});
.Ve
.Sp
Adds an entry to an existing \fI\s-1MANIFEST\s0\fR unless its already there.
.Sp
\&\f(CW$file\fR will be normalized (ie. Unixified).  \fB\s-1UNIMPLEMENTED\s0\fR
.Sh "\s-1MANIFEST\s0"
.IX Subsection "MANIFEST"
A list of files in the distribution, one file per line.  The \s-1MANIFEST\s0
always uses Unix filepath conventions even if you're not on Unix.  This
means \fIfoo/bar\fR style not \fIfoo\ebar\fR.
.PP
Anything between white space and an end of line within a \f(CW\*(C`MANIFEST\*(C'\fR
file is considered to be a comment.  Any line beginning with # is also
a comment.
.PP
.Vb 3
\&    # this a comment
\&    some/file
\&    some/other/file            comment about some/file
.Ve
.Sh "\s-1MANIFEST\s0.SKIP"
.IX Subsection "MANIFEST.SKIP"
The file \s-1MANIFEST\s0.SKIP may contain regular expressions of files that
should be ignored by \fImkmanifest()\fR and \fIfilecheck()\fR. The regular
expressions should appear one on each line. Blank lines and lines
which start with \f(CW\*(C`#\*(C'\fR are skipped.  Use \f(CW\*(C`\e#\*(C'\fR if you need a regular
expression to start with a \f(CW\*(C`#\*(C'\fR.
.PP
For example:
.PP
.Vb 5
\&    # Version control files and dirs.
\&    \ebRCS\eb
\&    \ebCVS\eb
\&    ,v$
\&    \eB\e.svn\eb
\&
\&    # Makemaker generated files and dirs.
\&    ^MANIFEST\e.
\&    ^Makefile$
\&    ^blib/
\&    ^MakeMaker\-\ed
\&
\&    # Temp, old and emacs backup files.
\&    ~$
\&    \e.old$
\&    ^#.*#$
\&    ^\e.#
.Ve
.PP
If no \s-1MANIFEST\s0.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 \s-1MANIFEST\s0.SKIP file.
.PP
In one's own \s-1MANIFEST\s0.SKIP file, certain directives
can be used to include the contents of other \s-1MANIFEST\s0.SKIP
files. At present two such directives are recognized.
.IP "#!include_default" 4
.IX Item "#!include_default"
This inserts the contents of the default \s-1MANIFEST\s0.SKIP file
.IP "#!include /Path/to/another/manifest.skip" 4
.IX Item "#!include /Path/to/another/manifest.skip"
This inserts the contents of the specified external file
.PP
The included contents will be inserted into the \s-1MANIFEST\s0.SKIP
file in between \fI#!start included /path/to/manifest.skip\fR
and \fI#!end included /path/to/manifest.skip\fR markers.
The original \s-1MANIFEST\s0.SKIP is saved as \s-1MANIFEST\s0.SKIP.bak.
.Sh "\s-1EXPORT_OK\s0"
.IX Subsection "EXPORT_OK"
\&\f(CW&mkmanifest\fR, \f(CW&manicheck\fR, \f(CW&filecheck\fR, \f(CW&fullcheck\fR,
\&\f(CW&maniread\fR, and \f(CW&manicopy\fR are exportable.
.Sh "\s-1GLOBAL\s0 \s-1VARIABLES\s0"
.IX Subsection "GLOBAL VARIABLES"
\&\f(CW$ExtUtils::Manifest::MANIFEST\fR defaults to \f(CW\*(C`MANIFEST\*(C'\fR. Changing it
results in both a different \f(CW\*(C`MANIFEST\*(C'\fR and a different
\&\f(CW\*(C`MANIFEST.SKIP\*(C'\fR file. This is useful if you want to maintain
different distributions for different audiences (say a user version
and a developer version including \s-1RCS\s0).
.PP
\&\f(CW$ExtUtils::Manifest::Quiet\fR defaults to 0. If set to a true value,
all functions act silently.
.PP
\&\f(CW$ExtUtils::Manifest::Debug\fR defaults to 0.  If set to a true value,
or if \s-1PERL_MM_MANIFEST_DEBUG\s0 is true, debugging output will be
produced.
