NAME

       Pod::Find - find POD documents in directory trees

SYNOPSIS

	 use Pod::Find qw(pod_find simplify_name);
	 my %pods = pod_find({ -verbose => 1, -inc => 1 });
	 foreach(keys %pods) {
	    print "found library POD `$pods{$_}' in $_
";
	 }

	 print "podname=",simplify_name('a/b/c/mymodule.pod'),"
";

	 $location = pod_where( { -inc => 1 }, "Pod::Find" );

DESCRIPTION

       Pod::Find provides a set of functions to locate POD files.  Note that no function is exported by default to avoid pollution of your names-
       pace, so be sure to specify them in the use statement if you need them:

	 use Pod::Find qw(pod_find);

       "pod_find( { %opts } , @directories )"

       The function pod_find searches for POD documents in a given set of files and/or directories. It returns a hash with the file names as keys
       and the POD name as value. The POD name is derived from the file name and its position in the directory tree.

       E.g. when searching in $HOME/perl5lib, the file $HOME/perl5lib/MyModule.pm would get the POD name MyModule, whereas
       $HOME/perl5lib/Myclass/Subclass.pm would be Myclass::Subclass. The name information can be used for POD translators.

       Only text files containing at least one valid POD command are found.

       A warning is printed if more than one POD file with the same POD name is found, e.g. CPAN.pm in different directories. This usually indi-
       cates duplicate occurrences of modules in the @INC search path.

       OPTIONS The first argument for pod_find may be a hash reference with options. The rest are either directories that are searched recursively
       or files.  The POD names of files are the plain basenames with any Perl-like extension (.pm, .pl, .pod) stripped.

       "-verbose => 1"
	   Print progress information while scanning.

       "-perl => 1"
	   Apply Perl-specific heuristics to find the correct PODs. This includes stripping Perl-like extensions, omitting subdirectories that are
	   numeric but do not match the current Perl interpreter's version id, suppressing site_perl as a module hierarchy name etc.

       "-script => 1"
	   Search for PODs in the current Perl interpreter's installation scriptdir. This is taken from the local Config module.

       "-inc => 1"
	   Search for PODs in the current Perl interpreter's @INC paths. This automatically considers paths specified in the "PERL5LIB" environ-
	   ment as this is prepended to @INC by the Perl interpreter itself.

       "simplify_name( $str )"

       The function simplify_name is equivalent to basename, but also strips Perl-like extensions (.pm, .pl, .pod) and extensions like .bat, .cmd
       on Win32 and OS/2, or .com on VMS, respectively.

       "pod_where( { %opts }, $pod )"

       Returns the location of a pod document given a search directory and a module (e.g. "File::Find") or script (e.g. "perldoc") name.

       Options:

       "-inc => 1"
	   Search @INC for the pod and also the "scriptdir" defined in the Config module.

       "-dirs => [ $dir1, $dir2, ... ]"
	   Reference to an array of search directories. These are searched in order before looking in @INC (if -inc). Current directory is used if
	   none are specified.

       "-verbose => 1"
	   List directories as they are searched

       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 automati-
       cally if required.

       A subdirectory pod/ is also checked if it exists in any of the given search directories. This ensures that e.g. perlfunc is found.

       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 'NAME' entry.

       A check is made to make sure that the file that is found does contain some pod documentation.

       "contains_pod( $file , $verbose )"

       Returns true if the supplied filename (not POD module) contains some pod information.
