+ Usage instructions for applications calling the sqlite3 API functions:
+
+ In your application, call sqlite3_enable_load_extension(db,1) to
+ allow loading external libraries. Then load the library libsqlitefunctions
+ using sqlite3_load_extension; the third argument should be 0.
+ See http://www.sqlite.org/cvstrac/wiki?p=LoadableExtensions.
+ Select statements may now use these functions, as in
+ SELECT cos(radians(inclination)) FROM satsum WHERE satnum = 25544;
+
+ Usage instructions for the sqlite3 program:
+
+ If the program is built so that loading extensions is permitted,
+ the following will work:
+ sqlite> SELECT load_extension('#{lib}/libsqlitefunctions.dylib');
+ sqlite> select cos(radians(45));
