+=head1 NAME
+
+CPT::Parameter
+
+=head1 VERSION
+
+version 1.99.4
+
+=head2 galaxy_command
+
+	$file_param->galaxy_command(); # where $file_param is a CPT::Parameter::*
+
+Returns the portion of the command used in the <command/> block in galaxy XML files
+
+=head2 getOptionsArray
+
+When called on a CPT::Parameter::* object, it will collapse the object into a GetOpt::Long compatible array
+
+=head2 getopt_identifier
+
+Used for backwards compatability with existing defaults => { 'file|f=s' => "Blah" }  format
+
+=head2 get_galaxy_identifier
+
+Returns the identifier associated with a given variable. This identifier is what the Cheetah template knows the variable as (given the correct context).
+
+For non-multiple variables it should be the name of the variable.
+
+For multiple variables it will reference the repeat item name and then the variable name (e.g., C< $item.label >)
+
+=head2 get_galaxy_cli_identifier
+
+Returns the command line identifier (i.e., the command line flag) associated
+with a given parameter. For a `--format` flag, this would return "format".
+This should work out of the box, as CLI parameters have the same name as we
+specify them with (even if they're repeated)
+
+=head2 is_optional
+
+If required, it is NOT optional; If not reqiured, it IS optional
+
+=head2 is_optional_galaxy
+
+Returns is_optional() as "True" or "False" for convenience and reduced code duplication
+
+=head2 update_index
+
+Convenience method to increment the index. This wraps around.
+
+=head2 reset_index
+
+convenience method to zero the index (i.e., the next get_value request will start at the beginning again)
+
+=head2 get_value
+
+Returns the value in the current index.
+
+=head2 get_default
+
+Returns the default in the current index. Something to note, please bear in
+mind this you are trying to access an array based on an index which wraps
+according to value() not according to default(). This means you may not reach
+the end of default/reach over the end of default depending on how many values
+the user actually passes
+
+=head2 validate
+
+Validation logic was eventually moved out here, as the logic for validaton is
+identical everywhere, and requires slightly different behaviour based on
+wheterh or not it's a single/multiple valued item.
+
+=head2 get_repeat_idx_name
+
+Function to obtain the name of the item as it is called inside the repeat. This
+is necessary to know which variable we are referring to within a loop.
+
+=head2 get_repeat_name
+
+Function to obtain the name of the repeat. It is necessary that this is used
+identically in the command section as well as in the input section.
+
+=head2 handle_possible_galaxy_input_repeat_start
+
+If the feature is repeated, this should automatically handle the start of that
+repeat
+
+=head2 handle_possible_galaxy_input_repeat_end
+
+If the feature is repeated, this should automatically handle the end of that
+repeat
+
+=head2 handle_possible_galaxy_command_repeat_start
+
+If the feature is repeated, this should automatically handle the start of that
+repeat with a
+
+    #for $item in $repeat_name:
+
+=head2 handle_possible_galaxy_command_repeat_end
+
+If the feature is repeated, this should automatically handle the end of that
