Description
       "Apache2::Module" provides the Perl API for creating and working with Apache modules

       See Apache Server Configuration Customization in Perl.

API
       "Apache2::Module" provides the following functions and/or methods:

       "add"

       Add a module's custom configuration directive to Apache.

         Apache2::Module::add($package, $cmds);

       arg1: $package ( string )
           the package of the module to add

       arg2: $cmds ( ARRAY of HASH refs )
           the list of configuration directives to add

       ret: no return value
       since: 2.0.00

       See also Apache Server Configuration Customization in Perl.

       "ap_api_major_version"

       Get the httpd API version this module was build against, not the module's version.

         $major_version = $module->ap_api_major_version();

       obj: $module ( "Apache2::Module object" )
       ret: $major_version ( integer )
       since: 2.0.00

       This methid is used to check that module is compatible with this version of the server before loading
       it.

       "ap_api_minor_version"

       Get the module API minor version.

         $minor_version = $module->ap_api_minor_version();

       obj: $module ( "Apache2::Module object" )
       ret: $minor_version ( integer )
       since: 2.0.00

       "ap_api_minor_version()" provides API feature milestones.

       It's not checked during module init.

       "cmds"

       Get the "Apache2::Command" object, describing all of the directives this module defines.

         $command = $module->cmds();

       obj: $module ( "Apache2::Module object" )
       ret: $command ( "Apache2::Command object" )
       since: 2.0.00

       "get_config"

       Retrieve a module's configuration. Used by configuration directives.

         $cfg = Apache2::Module::get_config($class, $server, $dir_config);
         $cfg = Apache2::Module::get_config($class, $server);
         $cfg =          $self->get_config($server, $dir_config);
         $cfg =          $self->get_config($server);

       obj: $module ( "Apache2::Module object" )
       arg1: $class ( string )
           The Perl package this configuration is for

       arg2: $server ( "Apache2::ServerRec object" )
           The current server, typically "$r->server" or "$parms->server".

       opt arg3: $dir_config ( "Apache2::ConfVector object" )
           By default, the configuration returned is the server level one. To retrieve the per directory
           configuration, use "$r->per_dir_config" as a last argument.

       ret: $cfg (HASH reference)
           A reference to the hash holding the module configuration data.

       since: 2.0.00

       See also Apache Server Configuration Customization in Perl.

       "find_linked_module"

       Find a module based on the name of the module

         $module = Apache2::Module::find_linked_module($name);

       arg1: $name ( string )
           The name of the module ending in ".c"

       ret: $module ( "Apache2::Module object" )
           The module object if found, "undef" otherwise.

       since: 2.0.00

       For example:

         my $module = Apache2::Module::find_linked_module('mod_ssl.c');

       "loaded"

       Determine if a certain module is loaded

         $loaded = Apache2::Module::loaded($module);

       name: $module ( string )
           The name of the module to search for.

           If $module ends with ".c", search all the modules, statically compiled and dynamically loaded.

           If $module ends with ".so", search only the dynamically loaded modules.

           If $module doesn't contain a ".", search the loaded Perl modules (checks %INC).

       ret: $loaded ( boolean )
           Returns true if the module is loaded, false otherwise.

       since: 2.0.00

       For example, to test if this server supports ssl:

         if (Apache2::Module::loaded('mod_ssl.c')) {
             [...]
         }

       To test is this server dynamically loaded mod_perl:

         if (Apache2::Module::loaded('mod_perl.so')) {
             [...]
         }

       To test if "Apache2::Status" is loaded:

         if (Apache2::Module::loaded('Apache2::Status')) {
             [...]
         }

       "module_index"

       Get the index to this modules structures in config vectors.

         $index = $module->module_index();

       obj: $module ( "Apache2::Module object" )
       ret: $index ( integer )
       since: 2.0.00

       "name"

       Get the name of the module's .c file

         $name = $module->name();

       obj: $module ( "Apache2::Module object" )
       ret: $name ( string )
       since: 2.0.00

       For example a mod_perl module, will return: mod_perl.c.

       "next"

       Get the next module in the list, "undef" if this is the last module in the list.

         $next_module = $module->next();

       obj: $module ( "Apache2::Module object" )
       ret: $next_module ( "Apache2::Module object" )
       since: 2.0.00

       "remove_loaded_module"

       Remove a module from the list of loaded modules permanently.

         $module->remove_loaded_module();

       obj: $module ( "Apache2::Module object" )
       ret: no return value
       since: 2.0.00

       "top_module"

       Returns the first module in the module list. Usefull to start a module iteration.

         $module = Apache2::Module::top_module();

       ret: $module ( "Apache2::Module object" )
       since: 2.0.00
