 description: {
 
-- Clone git repositories specified in source-repository-package stanzas
-  shallowly, since to build the package from the repository we only need to
-  read the commit specified. The rest of the repo is not needed.
-  Note that this does not change the behaviour of `cabal get -s`, which will
-  still clone the repository in full.
-- Clone VCS repositories concurrently, with a maximum of two concurrent tasks
-  at the same time (just like when downloading packages asynchronously)
