+#!/usr/bin/python
+
+"""Construct a GNU ld or Debian dpkg version-script from a set of
+RFC822-style symbol lists.
+
+Usage:
+ make-version-script.py [--symbols SYMBOLS] [--unreleased-version VER]
+ [--dpkg "LIBRARY.so.0 LIBRARY0 #MINVER#"]
+ [--dpkg-build-depends-package LIBRARY-dev]
+ [FILES...]
+
+Each FILE starts with RFC822-style headers "Version:" (the name of the
+symbol version, e.g. FOO_1.2.3) and "Extends:" (either the previous
+version, or "-" if this is the first version). Next there is a blank
+line, then a list of C symbols one per line.
+
+Comments (lines starting with whitespace + "#") are allowed and ignored.
+
+If --symbols is given, SYMBOLS lists the symbols actually exported by
+the library (one per line). If --unreleased-version is given, any symbols
+in SYMBOLS but not in FILES are assigned to that version; otherwise, any
+such symbols cause an error.
+
+If --dpkg is given, produce a Debian dpkg-gensymbols file instead of a
+GNU ld version-script. The argument to --dpkg is the first line of the
+resulting symbols file, and --dpkg-build-depends-package can optionally
+be used to set the Build-Depends-Package field.
+
+This script originates in telepathy-glib <http://telepathy.freedesktop.org/> -
+please send us any changes that are needed.
