Tip: comment out textbase locations in dbtwpub.ini
Comment out a textbase location line in dbtwpub.ini by preceding it with an exclamation point.
E.g.
!catalog=C:\Program Files\Inmagic\WebPubPro\Textbases
catalog=D:\Clients\Andornot\Textbases
Handy when you want to make a temporary change but want to switch back easy later.
UPDATE: Apparently the semicolon is what folks at Inmagic use to comment out lines in INI files, and is considered standard.
