       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 and third form can be used to check if the reconstruction is possible. It may fail if the on-
       disk data was 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 -ssequence 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.

       applydeltarpm was written to work on systems with limited memory.  It uses a paging algorithm to keep the
       size of in-core data low and not bring the system in an out-of-memory situation.
