--- Fetch back-end for retrieving sources from Git repositories
-- that use http:// transport. For example, for fetching a repository
-- that requires the following command line:
-- `git clone http://example.com/foo.git`
-- you can use this in the rockspec:
-- source = { url = "git+http://example.com/foo.git" }
-- Prefer using the normal git:// fetch mode as it is more widely
-- available in older versions of LuaRocks.
