Berkeley DB dependency

[Filip Janus]

Hello,
I am Fedora and RHEL database package maintainer. According to licence
policy of BerkeleyDB, where BerkeleyDB 6.x and later versions have a more
restrictive license than the previous versions (AGPLv3 vs. LGPLv2), and due
to that many projects cannot use it, there is an effort to replace Berkeley
DB by others databases(GDBM, SQLite,...). I would like to ask if exists in
Your project some possibility to use other backend database then BerkeleyDB
?

Thanks
Filip Januš
