@Leadwerks: Maybe add an argument to the program to tell it is being run from a host application and let the program exit with errorlevel if anything is not compiled properly or the like writing to the error pipe, so if someone uses this publisher from an ide, the ide can display any source code and line causing any possible error. The easiest way would be to bypass the bmk output using print statements, and the bmk error output to the error pipe, and also bypassing the errorlevel after compilation. It sounds more than it really is (I think).
