# Tests the requiring of gem code not as gems, but regular
# file system files.


# As an example, we can use this gem, change this to suit your system:
JSON_REQUIRE_SPEC='/Users/kbennett/.rvm/gems/ree-1.8.7-2010.02/gems/json-1.4.6/lib/json'

# Will change dir to the gem's directory before requiring it,
# and change dir back to original directory when done.
