.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fImkmanifest()\fR writes all files in and below the current directory to a
file named in the global variable \f(CW$ExtUtils::Manifest::MANIFEST\fR (which
defaults to \f(CW\*(C`MANIFEST\*(C'\fR) in the current directory. It works similar to
.PP
.Vb 1
\&    find . -print
.Ve
.PP
but in doing so checks each line in an existing \f(CW\*(C`MANIFEST\*(C'\fR file and
includes any comments that are found in the existing \f(CW\*(C`MANIFEST\*(C'\fR file
in the new one. Anything between white space and an end of line within
a \f(CW\*(C`MANIFEST\*(C'\fR file is considered to be a comment. Filenames and
comments are separated by one or more \s-1TAB\s0 characters in the
output. All files that match any regular expression in a file
\&\f(CW\*(C`MANIFEST.SKIP\*(C'\fR (if such a file exists) are ignored.
.PP
\&\fImanicheck()\fR 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 exits silently, returning 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.
.PP
\&\fIfilecheck()\fR 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.
.PP
\&\fIfullcheck()\fR does both a \fImanicheck()\fR and a \fIfilecheck()\fR, returning references
to two arrays, the first for files \fImanicheck()\fR found to be missing, the
seond for unexpeced files found by \fIfilecheck()\fR.
.PP
\&\fIskipcheck()\fR lists all the files that are skipped due to your
\&\f(CW\*(C`MANIFEST.SKIP\*(C'\fR file.
.PP
\&\fImanifind()\fR returns a hash reference. The keys of the hash are the
files found below the current directory.
.PP
maniread($file) 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.
.PP
\&\f(CW\*(C`manicopy($read,$target,$how)\*(C'\fR copies the files that are the keys in
the \s-1HASH\s0 \fI%$read\fR to the named target directory. The \s-1HASH\s0 reference
\&\f(CW$read\fR is typically returned by the \fImaniread()\fR function. This
function is useful for producing a directory tree identical to the
intended distribution tree. The third parameter \f(CW$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. Best is the default.
.SH "MANIFEST.SKIP"
.IX Header "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 sharp character. A typical example:
.PP
.Vb 4
\&    # Version control files and dirs.
\&    \ebRCS\eb
\&    \ebCVS\eb
\&    ,v$
.Ve
.PP
.Vb 5
\&    # Makemaker generated files and dirs.
\&    ^MANIFEST\e.
\&    ^Makefile$
\&    ^blib/
\&    ^MakeMaker-\ed
.Ve
.PP
.Vb 5
\&    # 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.
.SH "EXPORT_OK"
.IX Header "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 "GLOBAL VARIABLES"
.IX Header "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.
.SH "DIAGNOSTICS"
.IX Header "DIAGNOSTICS"
All diagnostic output is sent to \f(CW\*(C`STDERR\*(C'\fR.
.ie n .IP """Not in MANIFEST:""\fR \fIfile" 4
.el .IP "\f(CWNot in MANIFEST:\fR \fIfile\fR" 4

exist.
.ie n .IP """MANIFEST:""\fR \fI$!" 4
.el .IP "\f(CWMANIFEST:\fR \fI$!\fR" 4
.IX Item "MANIFEST: $!"

.ie n .IP """Added to MANIFEST:""\fR \fIfile" 4
.el .IP "\f(CWAdded to MANIFEST:\fR \fIfile\fR" 4
.IX Item "Added to MANIFEST: file"
is reported by \fImkmanifest()\fR if \f(CW$Verbose\fR is set and a file is added
to \s-1MANIFEST\s0. \f(CW$Verbose\fR is set to 1 by default.
