 ** This file is an amalgamation of many separate C source files from SQLite
-** version $VERSION.  By combining all the individual C code files into this 
+** version $VERSION.  By combining all the individual C code files into this
 ** single large file, the entire code can be compiled as a single translation
 ** unit.  This allows many compilers to do optimizations that would not be
 ** possible if the files were compiled separately.  Performance improvements
 ** of 5% or more are commonly seen when SQLite is compiled as a single
 ** translation unit.
 **
 ** This file is all you need to compile SQLite.  To use SQLite in other
 ** programs, you need this file and the "sqlite3.h" header file that defines
-** the programming interface to the SQLite library.  (If you do not have 
+** the programming interface to the SQLite library.  (If you do not have
 ** the "sqlite3.h" header file at hand, you will find a copy embedded within
 ** the text of this file.  Search for "Begin file sqlite3.h" to find the start
 ** of the embedded sqlite3.h header file.) Additional code files may be needed
 ** if you want a wrapper to interface SQLite with your choice of programming
 ** language. The code for the "sqlite3" command-line shell is also in a
 ** separate file. This file contains only code for the core SQLite library.
