 This module splits @file{ifile} into pieces. The output files will be named @file{<obase><xxx><suffix>}
 where @file{suffix} is the filename extension derived from the file format. @file{xxx} and the contents 
 of the output files depends on the chosen operator. 
+params is a comma separated list of processing parameters.
