DESCRIPTION

       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.

MODI

       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: Packages Release . .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.)

OPTIONS

       --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.

ENVIRONMENT

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