calc:

The purpose of this code is to show how to create programs
to run them on the DR. The program is a first attempt to get
a spreadsheet like program on the DR. Currently it can read
csv-files in the future more functionality might follow, buts
its main purpose is to act as an example.

Note that due to some limitation in the Python-port, the main-file to
load must be named 'python' (same as the executable) without any
extension.
