       applydeltarpm - reconstruct an rpm from a deltarpm

       applydeltarpm [-v] [-p] [-r oldrpm] deltarpm newrpm
       applydeltarpm -c|-C deltarpm
       applydeltarpm [-c|-C] -s sequence
       applydeltarpm -i deltarpm

       applydeltarpm applies a binary delta to either an old rpm or to on-disk
       data to re-create a new rpm. The old rpm can be specified with the -r
       option, if no rpm name is provided on-disk data is used. You can use -p
       to make applydeltarpm print the percentage of completion, or -v to make
       it more verbose about its operation.

       The second an third form can be used to check if the reconstruction is
       possible. It may fail if the on-disk data got changed (deltarpms are
       created in a way that config file changes do not matter) or the
       deltarpm does not match the rpm the delta was generated with. The -c
       option selects full (i.e. slow) on-disk checking, whereas -C only
       checks if the filesizes have not changed.

       Instead of a full deltarpm a sequence id can be given with the -s
       sequence option. Such an id contains all the information that is needed
       to do reconstruction checking.

       Finally information about a deltarpm can be printed with the -i option.

       applydeltarpm returns 0 if the rpm could be recreated or the checking
       succeeded, it returns 1 and prints an error message to stderr if
       something failed.
