# This is an example of using the Open Hub API from Ruby.
# Detailed information can be found at the Open Hub website:
#
#     https://github.com/blackducksoftware/ohloh_api
#
# This example uses the REXML library for XML parsing:
#
#     http://www.germane-software.com/software/rexml/
#

# This example retrieves basic Open Hub account information
# and outputs it as simple name: value pairs.
#
# Pass your Open Hub API key as the first parameter to this script.
# Open Hub API keys are free. If you do not have one, you can obtain one
# at the Open Hub website:
#
#     https://www.openhub.net/accounts/<your_login>/api_keys/new
#
# Pass the email address of the account as the second parameter to this script.
