Setup file information can be specified in the main input file. If SETINIT is specified, the next groups (to ENDSET), are assumed to be setup file information. The setup name will be the argument to SETINIT. Multiple setup files can be specified this way. An argument must be specified or the setup information will not be read.
If SETINIT is found, the end of the input group (everything up to the ``/'') is not considered the end of inputs for this file. The next inputs after the setup data are entered will continue to apply to the current file (usually the first).
Since SETUP can specify a file name, when there isn't an embedded setup file, it must be case sensitive. As a result, the case of the argument of SETINIT much match SETUP.
