* $Log: widget_text.h,v $
* Revision 1.3 2004/03/06 20:31:16 reinelt
* Complete rewrite of the evaluator to get rid of the code
* from mark Morley (because of license issues).
* The new Evaluator does a pre-compile of expressions, and
* stores them in trees. Therefore it should be reasonable faster...
*
* Revision 1.2 2004/01/15 07:47:03 reinelt
* debian/ postinst and watch added (did CVS forget about them?)
* evaluator: conditional expressions (a?b:c) added
* text widget nearly finished
*
* Revision 1.1 2004/01/15 04:29:45 reinelt
* moved lcd4linux.conf.sample to *.old
* lcd4linux.conf.sample with new layout
* new plugins 'loadavg' and 'meminfo'
* text widget have pre- and postfix
*
