The user of Brahms can control the program execution through the CERN FFREAD free format input package. By default both in the interactive and in the batch version a file with FFREAD cards is read in after the UBINIT, and before the UBSETR routine. All GEANT FFREAD cards are available and can be set.
The FFREAD cards file is read in through the ``generic'' name cardsfile. The user is expected to set a symbolic link from the actual file to this name.
