This script is not used by Subsyncit itself.

It is used when I check in Subsyncit so that there's a version number in the
source file. This is relevant as Python is a language that leaps into being
based on source files (unlike Java an its .class files), and I wanted to
have a version number in there just in case I'm supporting something.
