#
# This library is no longer being maintained, and is included for backward
# compatibility with Perl 4 programs which may require it.
#
# In particular, this should not be used as an example of modern Perl
# programming techniques.
#
# Suggested alternatives: Getopt::Long or Getopt::Std
#
;# Process single-character switches with switch clustering. Pass one argument
;# which is a string containing all switches that take an argument. For each
;# switch found, sets $opt_x (where x is the switch name) to the value of the
;# argument, or 1 if no argument. Switches which take an argument don't care
;# whether there is a space between the switch and the argument.
;# Usage:
;# do Getopt('oDI'); # -o, -D & -I take arg. Sets opt_* as a side effect.
