There is a sample script: src/general/g.parser/test.sh.

The general idea is:

1. Describe the module/options/flags by adding comments beginning with
"#%" to the start of the script. The field names match those in the
GModule, Option and Flag structs.

2. If the first argument isn't "@ARGS_PARSED@", invoke g.parser with
the script name and its arguments.

3. g.parser will parse the command line according to the comments from
step 1, then re-invoke the script with the value of each option/flag
stored in an environment variable called GIS_OPT_<option name> or
GIS_FLAG_<flag name>.
