+#
+# This library is no longer being maintained, and is included for backward
+# compatibility with Perl 4 programs which may require it.
+# This legacy library is deprecated and will be removed in a future
+# release of perl.
+#
+# 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.
