While Patron is written in portable Common Lisp in mind, because of some platform specific features (semaphores, missing threading features -- `THREAD-JOIN', `WITHOUT-INTERRUPTS', etc. -- in bordeaux-threads, `WITH-TIMEOUT' macro.) used, it currently works on SBCL and CCL platforms. As a side note, Patron currently depends on bordeaux-threads library for common threading functionalities.
For more information about the project and example code see README file.
