+# 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
+#
;# Usage:
;# do Getopts('a:bc'); # -a takes arg. -b & -c not. Sets opt_* as a
;# # side effect.
