I was looking to see if Berkeley DB or SQLite was in base. I found found SQLite3 in base but the headers are under a 'private' subdirectory (/usr/include/private). I have two questions. 1) Is there a simple C database (e.g. Berkeley DB) in base that I'm missing? and 2) am I correct to assume taking a dependency on something in private as being a "not good" idea?
