This is the source code for Clozure CL.
Because CCL is written in itself, you need an already-working version of CCL to compile it.
See https://github.com/Clozure/ccl/releases/latest for instructions on how to get a copy of CCL for your system.
To report a bug or request an enhancement, please make an issue at https://github.com/Clozure/ccl/issues.
If you have questions or run into problems, send mail to ccl-devel@clozure.com (see https://lists.clozure.com for instructions on how to subscribe), ask on #ccl on libera.chat, or create an issue here, especially if you think you have found a bug.
