Name:                husk-scheme
Version:             3.7
Synopsis:            R5RS Scheme interpreter, compiler, and library.
Description:         
  <<https://github.com/justinethier/husk-scheme/raw/master/docs/husk-scheme.png>>
  .
  A dialect of R5RS Scheme written in Haskell. Advanced 
  features are provided including:
  .
  * First-class continuations of unlimited extent
  .
  * Hygienic macros based on syntax-rules
  .
  * Low-level explicit renaming macros 
  .
  * A foreign function interface (FFI) to Haskell
  .
  * Full numeric tower providing support for real, rational, and complex numbers
  .
  * Proper tail recursion and lexical scoping
  .
  * Read-Eval-Print-Loop (REPL) interpreter, with input driven by Haskeline to provide a rich user experience
  .
  * Standard library of Scheme functions, and support for many popular SRFI's
  .
  Husk may be used as either a stand-alone interpreter or as an extension language within a larger Haskell application. By closely following the R5RS standard, the intent is to develop a Scheme that is as compatible as possible with other R5RS Schemes. Husk is mature enough for use in production applications, however it is not optimized for performance-critical applications. 
  .
  Scheme is one of two main dialects of Lisp. Scheme follows a minimalist design philosophy: the core language consists of a small number of fundamental forms which may be used to implement other built-in forms. Scheme is an excellent language for writing small, elegant programs, and may also be used to write scripts or embed scripting functionality within a larger application.
