- ;# 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.
