## Summary:

  The idea of this plugin is to provide functions for various kinds of 
context-free grammar parser generations with support for 
syntax-directed-translations (SDT) and semantic actions (SA) and the 
possibility of exporting parsers and translators (as generated stand-alone 
elisp code) to enable Emacs plugin-agnostic usage.
