62: ** unit. This allows many compilers to do optimizations that would not be
63: ** possible if the files were compiled separately. Performance improvements
64: ** of 5% or more are commonly seen when SQLite is compiled as a single
65: ** translation unit.
66: **
67: ** This file is all you need to compile SQLite. To use SQLite in other
68: ** programs, you need this file and the "sqlite3.h" header file that defines
69: ** the programming interface to the SQLite library. (If you do not have
70: ** the "sqlite3.h" header file at hand, you will find a copy embedded within
71: ** the text of this file. Search for "Begin file sqlite3.h" to find the start
72: ** of the embedded sqlite3.h header file.) Additional code files may be needed
73: ** if you want a wrapper to interface SQLite with your choice of programming
74: ** language. The code for the "sqlite3" command-line shell is also in a
75: ** separate file. This file contains only code for the core SQLite library.
