CSL processors

CSL processors are in development for several programming languages, with various degrees of completeness. Most complete and up-to-date is citeproc-js (Javascript), with support for the CSL 1.0 specification. citeproc-hs (Haskell) currently supports large parts of CSL 0.8. Other efforts include citeproc-php (PHP), citeproc-py (Python) and citeproc-rb (Ruby).
