Looks good!

Perhaps if --inputconfig flag is not set, it could check $OCIO? Might be a convenient way to verify the env is setup correctly, and may answer many "why doesn't OCIO work!" questions. Something like:

$ ociocheck
Checking $OCIO environment variable
Loading /wrong/path/to/config.ocio
Error: File does not exist
$ ociocheck -i /correct/path/to/config.ocio
Loading /correct/path/to/config.ocio ...

Could be useful when there env is less simple, such as inside applications that might be launched from wrapper scripts (e.g run subprocess.Popen("ociocheck") in Nuke's script editor)

Also, I wonder if requiring boost for the config-validation utility is reasonable? While I'm not fussed about the dependency, it seems like ociocheck is something that should always be available, even if built without the optional Boost. I guess the alternatives is to use something standalone like optparse.h, or copy that bit of boost?

ociocheck now does much better error checking.
It will test each colorspace and see which conversions conversions
to/from scene-linear work, and which do not.  This will catch
potential errors related to missing luts, etc.
