Once the user has written his code, he must interface it to ANALYSIS_CONTROL. This interface has two parts. First, the author must tell the analysis driver that his module exists. Second, he must provide a list specifying what modules (both standard and user-supplied) he wishes to include in his executable image. While the subroutines to interface a module to ANALYSIS_CONTROL can in fact be written by the code author, an interactive program exists that will automatically write this code. This program, BUILD_JOB, is described in CDF-386 and is the preferred method for code integration.
