jira4r

require 'xmlrpc/client'

# A useful helper for running JIRA XML-RPC from Ruby. Takes care of
# adding the token to each method call (so you can call server.getIssue(key)
# instead of server.getIssue(token, key)). Also takes care of re-logging in
# if your login times out.
#
# Usage:
#
# require 'jira4r'
# server = JIRA::Server.new("http://jira.atlassian.com")
# server.login("user", "password")
# puts server.getIssue("JRA-1000")
#
