# interface are omitted.) first do

# The make target above moves all of the source code files into
# a subdirectory named "tsrc".  (This script expects to find the files
# there and will not work if they are not found.)  There are a few
# generated C code files that are also added to the tsrc directory.
# For example, the "parse.c" and "parse.h" files to implement the
# the parser are derived from "parse.y" using lemon.  And the 
# "keywordhash.h" files is generated by a program named "mkkeywordhash".
#
# After the "tsrc" directory has been created and populated, run
# this script:
#
#      tclsh mksqlite3c.tcl
#
# The amalgamated SQLite code will be written into sqlite3.c

** 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 
** 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 "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.
