SimAn is released under the GNU public licence. In particular, your attention is drawn to the fact that it is distributed without any warranty, express or implied. If you are not familiar with the GNU public licence, please read it now.
I would be grateful if, during the pre-release phase, you provide me with your name and email and give me permission to email about major updates. However, you are under no obligation to do so - leave the form blank if you like.
Note that you can choose to download either the source (in a distutils-based package) or, if you're a Mac OS 10.5 Intel user, you can download a binary archive. As far as I can tell, this should also work for Mac OS 10.4 (Intel); if you have any success or otherwise trying such a thing please let me know.
The binary version should simply be extracted to the root folder (something like sudo tar -C / -xzf siman-0.2.macosx-10.5-i386.tar.gz should do it). The other source compilation procedure is described here.
Documentation —this is a little sketchy at the moment, but you can find a rough-and-ready tutorial here and some documentation built into the python module (standard python help system: type help(object) where object is the name of any object).
