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 instal-
     lation 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 ExtUtils::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 parame-
         ters are a list of directories. The directories returned
         will be restricted to those under the specified direc-
         tories.  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.
