NAME

       applydeltarpm - reconstruct an rpm from a deltarpm

SYNOPSIS

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

DESCRIPTION

       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 -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.

MEMORY CONSIDERATIONS

       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.

EXIT STATUS

       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.
