+# Modulator - Generate skeleton modules.
+#
+# The user fills out some forms with information about what the module
+# should support (methods, objects), names of these things, prefixes to
+# use for C code, whether the objects should also support access as numbers,
+# etc etc etc.
+# When the user presses 'Generate code' we generate a complete skeleton
+# module in C.
+#
+# Alternatively, the selections made can be save to a python sourcefile and
+# this sourcefile can be passed on the command line (resulting in the same
+# skeleton C code).
+#
+# Jack Jansen, CWI, October 1994.
