     Similar to rmtree, but removes only contents not the directory.
 
     This is useful e.g. when removing contents of current working directory.
     Deleting current working directory makes all further getcwd calls fail
     until chdir is called. chdir would be tricky in recipes, so we provide
     a call that doesn't delete the directory itself.
