    "The Tar program provides the ability to create tar archives, as well as
various other kinds of manipulation.  For example, you can use Tar on
previously created archives to extract files, to store additional files, or
to update or list files which were already stored.

Initially, tar archives were used to store files conveniently on magnetic
tape.  The name \"Tar\" comes from this use; it stands for tape archiver.
Despite the utility's name, Tar can direct its output to available devices,
files, or other programs (using pipes), it can even access remote devices or
files (as archives).")

   (description
    "GNU Diffutils is a package of several programs related to finding
differences between files.

Computer users often find occasion to ask how two files differ. Perhaps one
file is a newer version of the other file. Or maybe the two files started out
as identical copies but were changed by different people.

You can use the diff command to show differences between two files, or each
corresponding file in two directories. diff outputs differences between files
line by line in any of several formats, selectable by command line
options. This set of differences is often called a ‘diff’ or ‘patch’. For
files that are identical, diff normally produces no output; for
binary (non-text) files, diff normally reports only that they are different.

You can use the cmp command to show the offsets and line numbers where two
files differ. cmp can also show all the characters that differ between the
two files, side by side.

You can use the diff3 command to show differences among three files. When two
people have made independent changes to a common original, diff3 can report
the differences between the original and the two changed versions, and can
produce a merged file that contains both persons' changes together with
warnings about conflicts.

You can use the sdiff command to merge two files interactively.")
