NAME

Getopt::Gen::cmdline_pod.pm - built-in template for generating plain old documentation.

SYNOPSIS

 use Getopt::Gen::cmdline_pod;

 $og = Getopt::Gen::cmdline_pod->new(%args);
 $og->parse($options_file);
 $og->fill_in(%extra_text_template_fill_in_args);

DESCRIPTION

Generate pod documentation from option specifications.

METHODS

Most are inherited from Getopt::Gen.

• fill_in(%args)

  Just like the Getopt::Gen method, except you do not need to specify 'TYPE' or 'SOURCE' parameters.

BUGS

Probably many.

DESCRIPTION

[@ defined($og{USER}{details}) ? $og{USER}{details} : '' @]

CONFIGURATION FILES

Configuration files are expected to contain lines of the form:

    LONG_OPTION_NAME    OPTION_VALUE

where LONG_OPTION_NAME is the long name of some option, without the leading '--', and OPTION_VALUE is the value for that option, if any. Fields are whitespace-separated. Blank lines and comments (lines beginning with '#') are ignored.
