NAME

       combindeltarpm - combine multiple deltarpms to a single one

SYNOPSIS

       combinedeltarpm [-v] [-V version] [-z compression] [-S signaturerpm] olddeltarpms...  newdeltarpm

DESCRIPTION

       combinedeltarpm  creates  a new deltarpm from multiple old ones.  Applying the resulting deltarpm has the
       same effect as applying each of the old  ones  in  the  specified  order.  Use  the  -v  option  to  make
       combinedeltarpm more verbose about its work.

       combinedeltarpm  normally produces a V3 format deltarpm, use the -V option to specify a different version
       if desired. The -z option can be used to specify a different compression method, the default  is  to  use
       the same compression method as used in the last of the old deltarpms.

       If  you want to use a different header signature you can also specify a rpm with the -S option which will
       be used as signature reference. This feature can be used to if a deltarpm was made  against  an  unsigned
       rpm which was later signed.

MEMORY CONSIDERATIONS

       The  implementation  of combinedeltarpm currently unpacks the add-blocks of the deltarpms in memory, thus
       it needs about twice the uncompressed payload size of the target rpm.
