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