Running a single test

Dear all,

I am trying to investigate the remaining issue with OpenEXR 2.2.0 on
big endian arch. How am I supposed to run a single test.

Current log states:

$ cat IlmImfTest.log

There is almost no documentation for doing such trivial thing with
`test-driver`. I cannot re-run from the begining this machine is way
too slow ...

Thanks much
