                     Factor programming language

                             Why Factor

   The Factor programming language is a concatenative, stack-based
   programming language with high-level features including dynamic
   types, extensible syntax, macros, and garbage collection. On a
  practical side, Factor has a full-featured library, supports many
      different platforms, and has been extensively documented.

  The implementation is fully compiled for performance, while still
supporting interactive development. Factor applications are portable
     between all common platforms. Factor can deploy stand-alone
   applications on all platforms. Full source code for the Factor
              project is available under a BSD license.
