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 rsulting deltarpm has the same effect as
       applying each of the old ones in the specifed 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 sig-
       nature reference. This feature can be used to if a deltarpm was made against an unsigned rpm which later got 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.
