NAME
       debdelta-upgrade  -  Downloads  all deltas that may be used to ’apt-get
       upgrade’, and apply them.


SYNOPSIS
       debdelta-upgrade [OPTION]... [PACKAGE] ...


DESCRIPTION
       This program is designed to download changes (deltas) that may be  used
       to  apt-get upgrade all listed packages, and apply them.  If no package
       is listed in the command line, then it will  apply  to  all  upgradable
       packages. See debdelta(1) for more details on the delta files.


OPTIONS
       --dir DIR     directory where to save results.
                   (default: /var/cache/apt/archives for root,
                   /tmp/archive for non-root users)

       --deb-policy POLICY   policy to decide which debs to download,
                it is a comma separated list of (abbreviations of)
                  source =  there is no /etc/debdelta/sources.conf line
                  big =  the delta is too big
                  error =  the delta fails to apply
                  unavailable = all other cases
                  after = continue downloading debs after patching has ended
                default is s,b,e

       -v            verbose (can be added multiple times).

       -d            add extra debugging checks.

       -k            keep temporary files (use for debugging).


EXAMPLES
       When  invoked  as  root,  apt-get update && debdelta-upgrade && apt-get
       upgrade will download delta files, recreate the needed Debian packages,
       and  then  upgrade your Debian host. When only slow Internet connection
       is available, the above procedure  may  be  significantly  faster  than
       "apt-get  update && apt-get upgrade".  (Use -v to see how much faster.)


SECURITY
       A Debian package that is recreated using debbdelta-upgrade is  byte-by-
       byte  identical  to  the  original  one;  when   "apt-get  upgrade"  is
       subsequently invoked, the cryptographic archive authentication  support
       (see  apt-secure(8)  )  will  guarantee  that  it  can be trusted to be
       installed.  Currently,  though,  the   delta   file   itself   is   not
       cryptograhically protected.
