 If the URL scheme starts with `git+`, the source will be downloaded as a git repo. The git download mode supports multiple parameters:
 
-- `~tag`: Specify which tag of the repo to check out.
-- `~branch`: Specify which branch of the repo to check out.
-- `~commit`: Specify which commit of the repo to check out.
+- `~rev`: Specify which revision of the repo to check out.
 - `~depth`: Specify what depth should be used when cloning the repo. Must be an integer.
 - `~name`: Specify the name of the directory into which the git repo should be cloned.
+- `~recursive`: If set to true, submodules will be cloned recursively. It is false by default.
