# Small event handler to automatically open URLs and file
# bug reports at a bugzilla of your choiche
# it uses XML-RPC interface, so you must have it enabled
#
# Before using you must define BUGZILLA_USER, BUGZILLA_PASS credentials,
# BUGZILLA_XMLRPC - uri of xmlrpc.cgi,
# BUGZILLA_PRODUCT, BUGZILLA_COMPONENT - a place in BTS for build bugs
# BUGZILLA_VERSION - version against which to report new bugs
