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 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 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  uncom-
       pressed payload size of the target rpm.
