# Ruby lib for working with the Hoptoad API's XML interface.  
# The first thing you need to set is the account name.  This is the same
# as the web address for your account.
#
#   Hoptoad.account = 'myaccount'
#
# Then, you should set the authentication token.
#
#   Hoptoad.token = 'abcdefg'
#
# If no token or authentication info is given, a HoptoadError exception will be raised.
#
# For more details, check out the hoptoad docs at http://hoptoadapp.com/pages/api.
#
# Find errors
#
#   Errors are paginated. You get 25 at a time.
#   errors = Hoptoad::Error.find(:all)
#
#   with pagination:
#   Hoptoad::Error.find(:all, :params => { :page => 2 })
#
#   find individual error by ID
#   Hoptoad::Error.find(44)
