Most sites document the Darshan log directory for their installation, but sometimes the path isn't easy to remember.

It would be nice if we had a simple way to report this path to the user. It could be an environment variable set by the software module, or maybe a utility could emit the compiled-in path. At any rate something that we could document in tutorials etc. that will work across sites without remembering the log path for each.

@robl and I noticed this as a user pain point at ATPESC 2018.
