We have a python script that, in addition to building the code for our products, also compiled the CHM. The script makes a call to the HTML Help compiler to build the CHM. Since upgrading to RH8, however, this script no longer works--the hhc file appears to have changed format from HTML to XML, and it's this change that seems to be causing the problems. If I look at the output of a build in the RH8 output window, it seems that there is some kind of preprocessing going on before calling the compiler. Is it still possible to perform a build via script or via command line?
