Hi Pavel, You are right it contains sqlite3.c and sqlite3.h. "if you run Linux then I believe SQLite can be compiled and work right away without any additional platform-specific tuning and learning of internal magic. ;-)"
My ultimate aim is not to program using SQLite. I just want to know the internals of it? How it works? How i can make a new wrapper around it so that my exsisting applications can use it without huge changes..
