   5 # files, so that we don't have to do this by hand on every test file.
   6 # It attempts to collect some diagnostic info about size and speed that
   7 # should be useful in the future as the library gets tuned for size
   8 # and speed.  In addition, it tests static and shared linkage, iff each

  17 ###     that file from here.  (Write that file with this in mind...)
