HOW TO USE bs.bat

1) edit bs.bat and set bison_simple to complete path to bison.simple file

2) put all files into a dir in path, or better in VC Studio
	go to Options->Dirs->Exe and put the dir in there, so
	no need to restart computer.

3) for all *.y files from your projects you have a custom build step.
   change bison reference to bs.bat AND REMOVE OPTION -S "path to bison.simple"
   if you have two lines (eg. an if ) remove the if and condition and the next line(s)
   now you should have only the bs.bat with options for bison
