Whats the deal with Athenas compressed project files?
Starting with version 0.8.050, Athena writes out its project files using compression. The files written are identical to the format used by the popular gzip program, using the highest level of compression. Athena and Artemis will import these files or uncompressed project files from earlier versions of Athena in a transparent manner. It is quite possible that the user will never even realize that this change in the project file format occured.
