       rredtool  is  a  tool  to  handle  a subset of ed patches in a safe way.  It is especially targeted at ed
       patches as used in Packages.diff and Sources.diff.  Is also  has  a  mode  supposed  to  be  called  from
       reprepro as Index Hook to generate and update a Packages.diff/Index file.

TMPDIR, TEMPDIR
              temporary files are created in $TEMPDIR if set, otherwise in $TMPDIR if set, otherwise in /tmp/.

       One of the following has to be given, so that rredtool know that to do.

       --version
              Print the version of this tool (or rather the version of reprepro which it is coming with).

       --help Print a short overview of the modi.

       --patch
              The  first  argument of rredtool is the file to patch, the other arguments are ed patches to apply
              on this one.

       --merge
              The arguments are treated as ed patches, which are merged into a single one.

       --reprepro-hook (or no other mode flag)
              Act as reprepro index hook to manage a Packages.diff/index file.  That means  it  expects  to  get
              exactly 4 arguments and writes the names of files to place into filedescriptor 3.

              If neither --patch nor --merge is given, this mode is used, so you can just put

               DebIndices:PackagesRelease..gz/usr/bin/rredtool

              into  reprepro's  conf/distributions file to have a Packages.diff directory generated.  (Note that
              you have to generate an uncompressed file (the single dot).  You will need to have patch, gzip and
              gunzip available in your path.)

--debug
              Print intermediate results or other details that might be interesting when trying  to  track  down
              bugs in rredtool but not intresting otherwise.

       --max-patch-count=count
              When generating a Packages.diff/Index file, put at most count patches in it (not counting possible
              apt workaround patches).

       -o|--output
              Not yet implemented.
