PortSystem 1.0
Name: ndiff
Version: 2.00
Category: math
Maintainers: nomaintainer
Description: compare putatively similar files
Long Description: ndiff assumes that you have two text files containing numerical values, and the two files are expected to be identical, or at least numerically similar. ndiff allows you to specify absolute and/or relative error tolerances for differences between numerical values in the two files, and then reports only the lines with values exceeding those tolerances. It also tells you by how much they differ.
