# We do NOT update erlang.spec or the git index at all.

# For now, take a look at the patch-list-*.txt files

# generated in the tmpdir manually copy and adapt them

# git rm -f otp-00*.patch

# mv tmp.foobar/otp-00*.patch .

# git add otp-00*.patch
|

# We could only automate this if we added the required patch
|
||
|
|
# specific spec file conditionals to the commit message somehow,
|
||
|
|
# and then had this script transfer the conditionals into erlang.spec.
