The parameter file
rhd.par also has the UIO format.
But it will be usually Fortran ``formatted'' (ASCII).
It contains a list of parameter entries.
which are collected in groups to make it easier to find an entry.
Otherwise, the order is arbitrary (except for the very first
fileform uio entry).
If there are more than one entry with the same name, the first occurrence
will be used by CO5BOLD.
But the doubling of entries is strongly discouraged because it will almost certainly
lead to confusion at some time. In addition, the IDL routine to read the parameter
file will fail with an error message.
Additional entries can be added if the names differ from the standard ones described below. Theses entries will be ignored by CO5BOLD but read by the IDL input routine. They can be used to provide comments, additional information about the model, or control parameters for further processing.
