REM By default, give dx a max heap size of 1 gig and a stack size of 1meg.
rem This can be overridden by using "-JXmx..." and "-JXss..." options below.

REM Capture all arguments that are not -J options.
REM Note that when reading the input arguments with %1, the cmd.exe
REM automagically converts --name=value arguments into 2 arguments "--name"
REM followed by "value". Dx has been changed to know how to deal with that.
