   4 # Script to do automated testing and data collection for various test
   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
   9 # has been enabled.

  14 ### XXX There are a lot of tests in here for OS-specific stuff.  If we
  15 ###     move to a 'configure.target' method of determining those extra
  16 ###     flags and whatnot, we can take out all those things and source
  17 ###     that file from here.  (Write that file with this in mind...)
  18
  19 ### XXX Note that breaking out of this with ^C will not work.  Dunno why.
