Version 0.2 was issued in May 2003 and made available on the web together with the user's manual first version.
A series of bug corrections and slight improvements made us switch at some point to version 0.3.
Just before sending the package to CTAN, we undertook a full review of the code and updated the manual accordingly. We call it version 0.4. It is the last release before a completely new version of the package, with many more options , which is currently under work.
