Embeddable Common-Lisp

Embeddable Common-Lisp is a FOSS (LGPLv2) implementation of the ANSI Common Lisp programming language which is highly portable and may be embedded in C/C++ applications allowing for interactive programming with these languages. Hacking on ECL is a great fun and rewarding by itself. Ability to devote more time for it's development would be great, and that's what the financial support can buy.
