It is an early version, but it has been well tested in practice already and is feature-complete for its fairly minimal goals as of now. The site has a link to a mailing list (Google Groups) for further discussion, if this interests you!
Thanks,

Since the original announcement, I have written a tutorial that allows
you try out your own SHPAML examples online:
http://shpaml.webfactional.com/tutorial/1
I have also fixed some minor bugs, removed some unneeded features, and
cleaned up the download process.
As this is a new project, feedback is especially welcome. You can
follow this link to find the mailing list:
