#  script to run tests on all relevant rubies, and valgrind on supported rubies.
#  outputs tests to `test.log` and valgrind output to `valgrind.log`.
#
#  requires `rvm` to be installed. sorry about that, multiruby dudes.
#
#  it's worth periodically using hoe-debugger's ability to generate
#  valgrind suppression files to remove spurious valgrind messages
#  (e.g., 1.9.3's glob_helper). ["rake test:valgrind:suppression"]
#

# I'd add rubinius, but rvm errors when building it on my machine. :(
