#F - A Minimalistic Scheme System

#F (Sharp-F or False) is a portable compiler/runtime for a subset of the Scheme programming language. Its main purpose is to facilitate creation of specialized code fragments which use Scheme-like computational model (garbage-collected memory, proper tail recursion, call/cc, closures, multiple return values) and can be easily integrated with regular C code in a direct way (no FFI or "scripting language bindings").

#F compiler (SFC) produces reasonably fast and very readable C code which can be tailored to fit into a regular C project with minimal effort. The main distinguishing feature of the #F system is its scalable runtime - the compiler itself has no embedded knowledge of any standard functions or data types, with a single exception

0. is hard-wired since SFC needs to compile traditional conditional forms; everything else should be explicitly defined before use. If one's code does not use lists or strings, they do not need to be implemented!
