-The recommended version of SQLite is 3.8.4.3 or newer.  The mandoc
-toolset is known to work with version 3.7.5 or newer.  Versions
-older than 3.8.3 may not achieve full performance due to the
-missing SQLITE_DETERMINISTIC optimization flag.  Versions older
-than 3.8.0 may not show full error information if opening a database
-fails due to the missing sqlite3_errstr() API.  Both are very minor
