.SH 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 \fBPackages.diff/Index\fP file.
.SH "MODI"
One of the following has to be given, so that rredtool know that to
do.
.TP
.B \-\-version
Print the version of this tool
(or rather the version of reprepro which it is coming with).
.TP
.B \-\-help
Print a short overview of the modi.
.TP
.B \-\-patch
The first argument of rredtool is the file to patch,
the other arguments are ed patches to apply on this one.
.TP
.B \-\-merge
The arguments are treated as ed patches, which are merged into
a single one.
.TP
.BR \-\-reprepro\-hook " (or no other mode flag)
Act as reprepro index hook to manage a \fBPackages.diff/index\fP 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

 \fBDebIndices: Packages Release . .gz /usr/bin/rredtool\fP

into reprepro's \fBconf/distributions\fP 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.)

.SH "OPTIONS"
