     """Extends the standard library argument parser to construct arguments based on configuration flags.
 
     The extended class is set up to facilitate piping of single positional arguments via stdin. For this reason, positional arguments should be added using the locally defined add_positional method instead of add_argument.
 
+    Long flag aliases for short flags are editable using the arg_long argument. Editing a non-existent short flag will produce no error and have no effect. Adding a long flag for a short flag that does not have an alias will also not have effect.

     Calls chainlib.cli.args.ArgumentParser.process_flags with arg_flags and env arguments, see the method's documentation for further details.
