Mapping an ENDF-6 formatted file performs a one-to-one comparison of each MF/MT section present in the file to those of other nuclear data libraries.
A match is found when two MF/MT sections in ASCII format are identical (line numbers are excluded):cmp [MF/MT-FILE1] [MF/MT-FILE2] --> exit status 0
The map reports the name of the earliest official release that matches the MF/MT section.
