cd vulcan/install/bin
$cat buildgen.license

Seems to be closed source license if compared with open source
definition (paragraph 7,8,9)
http://www.opensource.org/docs/definition.php
What will be the licensing future of it ? because it will
create problems with all Linux distributions (firebird's 3.0 buildgen
utility considered non-free like nvidia's drivers for example )
