|
# Usage
|
|
# - Call argparse after registering all Options and Commands.
|
|
#
|
|
#! Option Handlers: '-name', '--name'
|
|
# - $1 will be the exact key (The 'name' part of '-name', '--name').
|
|
# - $2 will be the value either assigned with = or as a second argument.
|
|
# - ARGPARSE_USED must be set to 1 if $2 was used by the handler.
|
|
# - A status code of 0 must be returned if parsing was successful.
|
|
# - A status code of 1 must be returned if parsing failed.
|
|
#
|
|
#! Command Handlers: 'name'
|
|
# - $1 will be the exact key ('name' part)
|
|
# - $2 will contain the remaining arguments.
|
|
# - ARGPARSE_USED must be set to the number of arguments used by the handler.
|
|
# - A status code of 0 must be returned if parsing was successful.
|
|
# - A status code of 1 must be returned if parsing failed.
