I maintain a number of eggs (libraries) for CHICKEN Scheme, some of which I wrote. If you use any of them, please contact me with any bug reports, feedback, or improvements.
In the following table, each egg name is linked to its page(s) on the CHICKEN wiki, which I consider the main documentation for the library.
All of these libraries are free software released under the MIT/X license.
