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 informa-
       tion.  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 .pack-
           lists 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 direc-
           tories. 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 spec-
           ified 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 mod-
           ule.

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

EXAMPLE
       See the example in ExtUtils::Packlist.
