Highpoint Software Systems, LLC, offers the Sage®
library free of charge for academic and in-house corporate development. For commercial for-sale products, we ask for a small royalty fee, or to be allowed to help construct the application.
We provide source code on a user (i.e. read-only) or a contributor (i.e. source code respository read/write
access) basis. Please Contact Highpoint
to obtain a current copy. We'll get back to you ASAP. In the meantime, maybe, check out our help file for an idea of what we've got.
We also, of course, provide training and consulting services at what we're sure you'll find to be reasonable rates.
