A commit can have multiple parents! You can specify the -p option multiple times, like this:
|
||
|
|
|
||
|
|
git commit-tree <tree> -m "Description" -p <parent1> -p <parent2>
|
||
|
|
|
||
|
|
Build a rhombus shape from commits, where two commits point to the same parent, and then a fourth commit points to both of them.
