Till, I just looked into the xpdf 3.02 sources (that is the version
currently in use at oursite) and found
static ArgDesc argDesc[] = {
...
{"-cfg", argString, cfgFileName, sizeof(cfgFileName),
"configuration file to use in place of .xpdfrc"},
...
};
in all of the utilities' main modules, e.g. in
pdftops.cxx
The config gile seems to be digested in a module GlobalParams.cc
