3 | # This library is no longer being maintained, and is included for backward | |
4 | # compatibility with Perl 4 programs which may require it. | |
5 | # | |
6 | # In particular, this should not be used as an example of modern Perl | |
7 | # programming techniques. | |
8 | # | |
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. | |
16 | ||
17 | ;# Usage: | |
18 | ;# do Getopt('oDI'); # -o, -D & -I take arg. Sets opt_* as a side effect. | |
