NAME
       xdeltadir - Invoke XDeltadir

SYNOPSIS
       xdeltadir subcommand [ operand...  ]

DESCRIPTION
       XDeltadir  is  a  perl script that wraps around the XDelta program.  XDeltadir provides the ability to generate deltas between files in the
       two directories and later apply those deltas.  It operates similar to the diff and patch commands, but works on binary files stored in  two
       different directories and does not produce a human readable output.

       XDeltadir has two subcommands, delta and patch. Delta accepts two directories and produces a delta, while patch accepts the original direc-
       tory and a delta and produces the other directory.  As opposed to the the diff(1) format, which can usually be reversed, these  deltas  are
       one way.

   Subcommands
       Each  subcommand  will  be  detailed  seperately.  In general, any input file may be compressed with gzip(1) and XDelta program called from
       XDeltadir will automatically uncompress it into a temporary location before examining the file. This temporary location is either the value
       of  the	environment  variable, if set, or "/tmp".  Unless turned off, XDelta always verifies the integrity of reconstructed files with MD5
       checksums.  By default, XDelta compresses constructed deltas.

   Delta
       The delta subcommand has the following synopsis:

       xdeltadir delta from_dir to_dir patch_dir

       Computes a deltas for the files from from_dir to to_dir and writes them to patch_dir

   Patch
       The patch subcommand has the following synopsis:

       xdeltadir patch patch_dir from_dir to_dir

       Applies patches from patch_dir to files from from_dir The from files must be identical to the ones used to  create  the	deltas.   Its  MD5
       checksum is used to verify this condition.  The constructed files and directories will be written to to_dir

       All the directories must exist before running the xdeltadir.
