Thanks for your help resolving my problem of pushing a gem to
RubyGems. Things are now working fine.
The gem I posted -- runmetric -- is fairly simple, but it simplifies
using the Benchmark library for programming challenges like at
ProjectEuler.net, which I have just started. I wanted to make it
available to other Ruby programmers at ProjectEuler (of which there
are 3392!!), as well as in the world at large.
Thanks, too, for all of the work you do on the Windows installer!!!
