This utility compares two input projection data sets. The input data are deemed identical if their maximum absolute difference is less than a hard-coded tolerance value. Diagnostic output is written to stdout, and the return value indicates if the files are identical or not. Note however that a non-success return value (which is 1 on most systems) might also indicate an error reading the data.
