96 This class does L<MooseX::Getopt::Parser> for L<MooseX::Getopt>. This
97 class is used by default if L<Getopt::Long::Descriptive> module is
104 =item B<build_options ($getopt, @attrs)>
106 This method parses the CLI options with L<Getopt::Long> and returns a hashref to options list.
108 The first argument have to be L<MooseX::Getopt::Session> object and
109 second argument is a list of attributes which contains options.
113 This accessor contains the arrayref to list with special configuration
114 keywords for L<Getopt::Long>.
120 All complex software has bugs lurking in it, and this module is no
121 exception. If you find a bug please either email me, or add the bug
