Getopt::Std
Processes single-character, command-line options with
option clustering. Exports two functions, which analyze @ARGV
, extract information about the
options, and return this information to your program in a set of
variables. Processing of @ARGV
stops when an argument without a leading -
is encountered, if that argument is not
associated with a preceding option. Otherwise, @ARGV
is processed to the end and left
empty.
