\&\fBPod::Find\fR provides a set of functions to locate \s-1POD\s0 files.  Note that
no function is exported by default to avoid pollution of your namespace,
so be sure to specify them in the \fBuse\fR statement if you need them:
.PP
.Vb 1
\&  use Pod::Find qw(pod_find);
.Ve
.PP
From this version on the typical \s-1SCM\s0 (software configuration management)
files/directories like \s-1RCS\s0, \s-1CVS\s0, \s-1SCCS\s0, .svn are ignored.
.ie n .SS """pod_find( { %opts } , @directories )"""
.el .SS "\f(CWpod_find( { %opts } , @directories )\fP"
.IX Subsection "pod_find( { %opts } , @directories )"
The function \fBpod_find\fR searches for \s-1POD\s0 documents in a given set of
files and/or directories. It returns a hash with the file names as keys
and the \s-1POD\s0 name as value. The \s-1POD\s0 name is derived from the file name
and its position in the directory tree.
.PP
E.g. when searching in \fI\f(CI$HOME\fI/perl5lib\fR, the file
\&\fI\f(CI$HOME\fI/perl5lib/MyModule.pm\fR would get the \s-1POD\s0 name \fIMyModule\fR,
whereas \fI\f(CI$HOME\fI/perl5lib/Myclass/Subclass.pm\fR would be
\&\fIMyclass::Subclass\fR. The name information can be used for \s-1POD\s0
translators.
.PP
Only text files containing at least one valid \s-1POD\s0 command are found.
.PP
A warning is printed if more than one \s-1POD\s0 file with the same \s-1POD\s0 name
is found, e.g. \fI\s-1CPAN\s0.pm\fR in different directories. This usually
indicates duplicate occurrences of modules in the \fI\f(CI@INC\fI\fR search path.
.PP
\&\fB\s-1OPTIONS\s0\fR The first argument for \fBpod_find\fR may be a hash reference
with options. The rest are either directories that are searched
recursively or files.  The \s-1POD\s0 names of files are the plain basenames
with any Perl-like extension (.pm, .pl, .pod) stripped.
.ie n .IP """\-verbose => 1""" 4
.el .IP "\f(CW\-verbose => 1\fR" 4
.IX Item "-verbose => 1"
Print progress information while scanning.
.ie n .IP """\-perl => 1""" 4
.el .IP "\f(CW\-perl => 1\fR" 4
.IX Item "-perl => 1"
Apply Perl-specific heuristics to find the correct PODs. This includes
stripping Perl-like extensions, omitting subdirectories that are numeric
but do \fInot\fR match the current Perl interpreter's version id, suppressing
\&\fIsite_perl\fR as a module hierarchy name etc.
.ie n .IP """\-script => 1""" 4
.el .IP "\f(CW\-script => 1\fR" 4
.IX Item "-script => 1"
Search for PODs in the current Perl interpreter's installation 
\&\fBscriptdir\fR. This is taken from the local Config module.
.ie n .IP """\-inc => 1""" 4
.el .IP "\f(CW\-inc => 1\fR" 4
.IX Item "-inc => 1"
Search for PODs in the current Perl interpreter's \fI\f(CI@INC\fI\fR paths. This
automatically considers paths specified in the \f(CW\*(C`PERL5LIB\*(C'\fR environment
as this is included in \fI\f(CI@INC\fI\fR by the Perl interpreter itself.
.ie n .SS """simplify_name( $str )"""
.el .SS "\f(CWsimplify_name( $str )\fP"
.IX Subsection "simplify_name( $str )"
The function \fBsimplify_name\fR is equivalent to \fBbasename\fR, but also
strips Perl-like extensions (.pm, .pl, .pod) and extensions like
\&\fI.bat\fR, \fI.cmd\fR on Win32 and \s-1OS/2\s0, or \fI.com\fR on \s-1VMS\s0, respectively.
.ie n .SS """pod_where( { %opts }, $pod )"""
.el .SS "\f(CWpod_where( { %opts }, $pod )\fP"
.IX Subsection "pod_where( { %opts }, $pod )"
Returns the location of a pod document given a search directory
and a module (e.g. \f(CW\*(C`File::Find\*(C'\fR) or script (e.g. \f(CW\*(C`perldoc\*(C'\fR) name.
.PP
Options:
.ie n .IP """\-inc => 1""" 4
.el .IP "\f(CW\-inc => 1\fR" 4
.IX Item "-inc => 1"
Search \f(CW@INC\fR for the pod and also the \f(CW\*(C`scriptdir\*(C'\fR defined in the
Config module.
.ie n .IP """\-dirs => [ $dir1, $dir2, ... ]""" 4
.el .IP "\f(CW\-dirs => [ $dir1, $dir2, ... ]\fR" 4
.IX Item "-dirs => [ $dir1, $dir2, ... ]"
Reference to an array of search directories. These are searched in order
before looking in \f(CW@INC\fR (if \fB\-inc\fR). Current directory is used if
none are specified.
.ie n .IP """\-verbose => 1""" 4
.el .IP "\f(CW\-verbose => 1\fR" 4
.IX Item "-verbose => 1"
List directories as they are searched
.PP
Returns the full path of the first occurrence to the file.
Package names (eg 'A::B') are automatically converted to directory
names in the selected directory. (eg on unix 'A::B' is converted to
\&'A/B'). Additionally, '.pm', '.pl' and '.pod' are appended to the
search automatically if required.
.PP
A subdirectory \fIpod/\fR is also checked if it exists in any of the given
search directories. This ensures that e.g. perlfunc is
found.
.PP
It is assumed that if a module name is supplied, that that name
matches the file name. Pods are not opened to check for the '\s-1NAME\s0'
entry.
.PP
A check is made to make sure that the file that is found does 
contain some pod documentation.
.ie n .SS """contains_pod( $file , $verbose )"""
.el .SS "\f(CWcontains_pod( $file , $verbose )\fP"
.IX Subsection "contains_pod( $file , $verbose )"
Returns true if the supplied filename (not \s-1POD\s0 module) contains some pod
information.
