BKchem is a chemical drawing program written in Python. The documentation as well as the
	program itself are in constant development. Therefor this manual is not meant to be
	complete, but rather tries to cover the very basics and the things that are not easy to find
	out without help. On the other hand many things are so self-evident that it would be useless
	to describe them. If you find that something you would like to know is not described in this
	manual, please email me to <beda@zirael.org>.
