      3 # Tests for the special target .DELETE_ON_ERROR in dependency declarations,
      4 # which controls whether the target is deleted if a shell command fails or
      5 # is interrupted.
      6 #
      7 # In compatibility mode, regular and phony targets are deleted, but precious
      8 # targets are preserved.
      9 #
     10 # In parallel mode, regular targets are deleted, while phony and precious
     11 # targets are preserved.
