System name: plc2c
This package does NOT want to apply for inclusion in the GNU project

A GCC front end to compile IEC 61131-3 languages.

IEC 61131-3 is the first real endeavor to standardize programming languages for 
industrial automation in Programmable Logic Controllers (PLCs).

The standard (was IEC 1131 before renumbering) calls for 5 different languages 
and a common set of data typing, variables, and standard functions and function 
blocks.

ST - Structured Text - a high level language
IL - Instruction List - an assembly like language
FBD - Function Block Diagram – encapsulation into black boxes
LD - Ladder Diagram – from relay ladder logic
SFC - Sequential Flow Chart –overall control of program flow

It does not exist yet but I\'m working on it.
