Thanks, but my use case is to have a number of erlang installations
and detect which version each is (looking at the directory name
doesn't always help). 0.15s*5 is noticeable and it's not that fast on
all filesystems (think clearcase)... Of course, I have this workaround
as backup. The issue is that the information was available before, but
is going away now with the new version scheme.

Vlad
