This project requires all contributors to assert that their contributions
|
||
|
|
are provided in compliance with the terms of the Developer's Certificate
|
||
|
|
of Origin 1.1 (DCO):
|
||
|
|
|
||
|
|
https://developercertificate.org/
|
||
|
|
|
||
|
|
To indicate acceptance of the DCO every commit must have a tag
|
||
|
|
|
||
|
|
Signed-off-by: REAL NAME <EMAIL>
|
||
|
|
|
||
|
|
This can be achieved by passing the "-s" flag to the "git commit" command.
|
||
|
|
|
||
|
|
To bulk update all commits on current branch "git rebase" can be used:
|
||
|
|
|
||
|
|
git rebase -i master -x 'git commit --amend --no-edit -s'
|
||
|
|
|
||
|
|
""")
|
||
|
|
|
||
|
|
sys.exit(1)
|
||
|
|
|
||
|
|
sys.exit(0)
