This is a patch file to create version $curr_ver from $prev_ver.
|
|
|
|
Please check the signature of this patch file:
|
|
|
|
zcat somepath/$pack-$prev_ver-$curr_ver.diff.gz | gpg --verify
|
|
|
|
Change to directory $pack-$prev_ver (or however you renamed it)
|
|
and give this command:
|
|
|
|
zcat somepath/$pack-$prev_ver-$curr_ver.diff.gz | patch -p1
|
|
|
|
It is a good idea to rename your current directory to $pack-$curr_ver now.
