  17 # This test checks that dependent files are updated before including
  18 # in the distribution. `parse.c' depends on `parce.y'. The later is
  19 # updated so that `parse.c' should be rebuild. Then we are running
  20 # `make' and `make distdir' and check whether the version of `parse.c'
  21 # to be distributed is up to date.
