NAME

       ExtUtils::Installed - Inventory management of installed modules

SYNOPSIS

	  use ExtUtils::Installed;
	  my ($inst) = ExtUtils::Installed->new();
	  my (@modules) = $inst->modules();
	  my (@missing) = $inst->validate("DBI");
	  my $all_files = $inst->files("DBI");
	  my $files_below_usr_local = $inst->files("DBI", "all", "/usr/local");
	  my $all_dirs = $inst->directories("DBI");
	  my $dirs_below_usr_local = $inst->directory_tree("DBI", "prog");
	  my $packlist = $inst->packlist("DBI");

DESCRIPTION

       ExtUtils::Installed  provides a standard way to find out what core and module files have been installed.  It uses the information stored in
       .packlist files created during installation to provide this information.  In addition it provides facilities to classify the installed
       files and to extract directory information from the .packlist files.

USAGE

       The new() function searches for all the installed .packlists on the system, and stores their contents. The .packlists can be queried with
       the functions described below.

FUNCTIONS

       new()
	   This takes no parameters, and searches for all the installed .packlists on the system.  The packlists are read using the ExtU-
	   tils::packlist module.

       modules()
	   This returns a list of the names of all the installed modules.  The perl 'core' is given the special name 'Perl'.

       files()
	   This takes one mandatory parameter, the name of a module.  It returns a list of all the filenames from the package.	To obtain a list
	   of core perl files, use the module name 'Perl'.  Additional parameters are allowed.	The first is one of the strings "prog", "doc" or
	   "all", to select either just program files, just manual files or all files.	The remaining parameters are a list of directories. The
	   filenames returned will be restricted to those under the specified directories.

       directories()
	   This takes one mandatory parameter, the name of a module.  It returns a list of all the directories from the package.  Additional
	   parameters are allowed.  The first is one of the strings "prog", "doc" or "all", to select either just program directories, just manual
	   directories or all directories.  The remaining parameters are a list of directories. The directories returned will be restricted to
	   those under the specified directories.  This method returns only the leaf directories that contain files from the specified module.

       directory_tree()
	   This is identical in operation to directories(), except that it includes all the intermediate directories back up to the specified
	   directories.

       validate()
	   This takes one mandatory parameter, the name of a module.  It checks that all the files listed in the modules .packlist actually exist,
	   and returns a list of any missing files.  If an optional second argument which evaluates to true is given any missing files will be
	   removed from the .packlist

       packlist()
	   This returns the ExtUtils::Packlist object for the specified module.

       version()
	   This returns the version number for the specified module.

EXAMPLE

       See the example in ExtUtils::Packlist.
