REM Please note that I have NOT tested Zenity/Wenity in a Windows environment.
REM I've used the example files from the programs to create this, though.
REM You do not need to alter the variables below if the files are in your path or you're just
REM using the command line interface.
REM
REM If Zenity is installed/desired, /z should be the first argument.
REM You should edit this file and put the path to zenity.exe in the line below!
set ZENITYPATH=c:\PATH\TO\zenity.exe
REM Get Zenity here:
REM Windows port of Zenity: http://www.placella.com/software/zenity/
REM
REM Get Wenity here:
REM http://kksw.zzl.org/wenity.html
REM If Wenity (a Java Zenity clone) is installed/desired, /w should be the first argument.
REM You should edit this file and put the path to the wenity.jar file in the line below!
set WENITYPATH=c:\PATH\TO\wenity.jar
REM Please remember that Java must be installed properly and found by your path to use Wenity.
REM You can specify the path to java.exe on the line below.
set JAVAEXE=c:\PATH\TO\java.exe
