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. Where it searches by default is
       determined by the settings found in %Config::Config, and what the value
       is of the PERL5LIB environment variable.

METHODS
       Unless specified otherwise all method can be called as class methods,
       or as object methods. If called as class methods then the "default"
       object will be used, and if necessary created using the current
       processes %Config and @INC.  See the 'default' option to new() for
       details.

       new()
           This takes optional named parameters. Without parameters, this
           searches for all the installed .packlists on the system using
           information from %Config::Config and the default module search
           paths @INC. The packlists are read using the ExtUtils::Packlist
           module.

           If the named parameter "config_override" is specified, it should be
           a reference to a hash which contains all information usually found
           in %Config::Config. For example, you can obtain the configuration
           information for a separate perl installation and pass that in.

               my $yoda_cfg  = get_fake_config('yoda');
               my $yoda_inst = ExtUtils::Installed->new(config_override=>$yoda_cfg);

           Similarly, the parameter "inc_override" may be a reference to an
           array which is used in place of the default module search paths
           from @INC.

               use Config;
               my @dirs = split(/\Q$Config{path_sep}\E/, $ENV{PERL5LIB});
               my $p5libs = ExtUtils::Installed->new(inc_override=>\@dirs);

           Note: You probably do not want to use these options alone, almost
           always you will want to set both together.

           The parameter c<extra_libs> can be used to specify additional paths
           to search for installed modules. For instance

               my $installed = ExtUtils::Installed->new(extra_libs=>["/my/lib/path"]);

           This should only be necessary if "/my/lib/path" is not in PERL5LIB.

           Finally there is the 'default', and the related 'default_get' and
           'default_set' options. These options control the "default" object
           which is provided by the class interface to the methods. Setting
           "default_get" to true tells the constructor to return the default
           object if it is defined. Setting "default_set" to true tells the
           constructor to make the default object the constructed object.
           Setting the "default" option is like setting both to true. This is
           used primarily internally and probably isn't interesting to any
           real user.

       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.
