+# genrpbindings -- generate ratpoison bindings for various languages
+#

+# Tue Dec 4 16:15:53 PST 2001
+#
+# currently generates bindings for:
+# * Perl (Ratpoison.pm)
+# * Emacs Lisp (ratpoison-cmd.el)
+#
+# add more languages!
+#
+# Bindings are just very thin wrappers, no argument checking is done.
+# All of the functions return a string.
+#
+# Example: ratpoison --command='echo hello world'
+#
+# #!perl
+# use Ratpoison;
+# Ratpoison::echo ("hello world")
+#
+# ;;; elisp
+# (require 'ratpoison-cmd)
+# (ratpoison-echo "hello world")
