2013-01-21 15:36 AEST by Arthur Barrett - There are various good reasons to have an sqlite database in CVSNT server, particularly to store val_tags 
robustly.

see:
bug 6388 - enh: delete / rename branches by listing in val_tags sqlite
bug 6012 - enh: RCS revisions should have a sequence
bug 6388 - enh: checkout branch that does not exist - give warning
bug 6637 - enh: WM (or TCVS): branch/merge 'module' view
