%description
    Patchutils is a small collection of programs that operate on
    patch files. Interdiff generates an incremental patch from two
    patches against a common source. For example, if you have applied
    a pre-patch to a source tree, and wish to apply another pre-patch
    (which is against the same original source tree), you can use
    interdiff to generate the patch that you need to apply. You can also
    use this to review changes between two pre-patches. Combinediff
    generates a single patch from two incremental patches, allowing you
    to merge patches together. The resulting patch file only alters each
    file once. Filterdiff will select the portions of a patch file that
    apply to files matching (or, alternatively, not matching) a shell
    wildcard. Fixcvsdiff is for correcting the output of 'cvs diff'.
    Rediff corrects hand-edited patches, by comparing the original patch
    with the modified one and adjusting the offsets and counts. Lsdiff
    displays a short listing of affected files in a patch file, along
    with (optionally) the line numbers of the start of each patch.
    Splitdiff separates out patches from a patch file so that each new
    patch file only alters any given file once. In this way, a file
    containing several incremental patches can be split into individual
    incremental patches.
