This is the simple main  program   of  swipl.exe; the SWI-Prolog console
application. It can be used as   a  basis for console-based applications
that have SWI-Prolog embedded.

The default version does Control-C  processing   and  decodes ANSI color
sequences to support colors in the console window.
