15 combinedeltarpm creates a new deltarpm from multiple old ones. Apply‐
16 ing the resulting deltarpm has the same effect as applying each of the
17 old ones in the specified order. Use the -v option to make com‐
18 binedeltarpm more verbose about its work.
19
20 combinedeltarpm normally produces a V3 format deltarpm, use the -V
21 option to specify a different version if desired. The -z option can be
22 used to specify a different compression method, the default is to use
23 the same compression method as used in the last of the old deltarpms.
24
25 If you want to use a different header signature you can also specify a
26 rpm with the -S option which will be used as signature reference. This
27 feature can be used to if a deltarpm was made against an unsigned rpm
28 which later got signed.

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