CCAIN is a lightweight component framework written entirely in C and inspired by the Common Component Architecture (CCA) component model. The CCA-Lite effort (of which CCAIN played a small role) has been revised and is now focused on automation of code generation and manipulation tools. These tools are known as the CCA "Onramp" project, with a goal of helping kickstart new users into the CCA world with minimal pain and confusion. Onramp will be available from the SciDAC Outreach web site.

CCAIN may still be of interest to people who seek a minimal C framework for component programming, so check it out if you're curious.
