No. The repository can be viewed online:
http://firebird.cvs.sourceforge.net/viewvc/firebird/firebird2/doc/sql.extensions/README.universal_triggers?revision=1.3&view=markup&pathrev=MAIN

You could also download the ZIP distribution, unpack it and open
doc/sql.extensions/readme.universal_triggers.txt
