- Simplified interface for SQLite.
- Updated for Sqlite 3 by Tim Anderson (tim@itwriting.com)
- Note: NOT COMPLETE for version 3, just minimal functionality
- Adapted from file created by Pablo Pissanetzky (pablo@myhtpc.net)
- which was based on SQLite.pas by Ben Hochstrasser (bhoc@surfeu.ch)

-// In the SQL strings input to sqlite3_prepare() and sqlite3_prepare16(),
-// one or more literals can be replace by a wildcard "?" or ":N:" where
-// N is an integer. These value of these wildcard literals can be set
-// using the routines listed below.
-//
-// In every case, the first parameter is a pointer to the sqlite3_stmt
-// structure returned from sqlite3_prepare(). The second parameter is the
-// index of the wildcard. The first "?" has an index of 1. ":N:" wildcards
-// use the index N.
-//
-// The fifth parameter to sqlite3_bind_blob(), sqlite3_bind_text(), and
-//sqlite3_bind_text16() is a destructor used to dispose of the BLOB or
-//text after SQLite has finished with it. If the fifth argument is the
-// special value SQLITE_STATIC, then the library assumes that the information
-// is in static, unmanaged space and does not need to be freed. If the
-// fifth argument has the value SQLITE_TRANSIENT, then SQLite makes its
-// own private copy of the data.
-//
-// The sqlite3_bind_* routine must be called before sqlite3_step() after
-// an sqlite3_prepare() or sqlite3_reset(). Unbound wildcards are interpreted
-// as NULL.
