+# To build a single huge source file holding all of SQLite (or at

+#      make target_source
+#
+# 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

+# comment of the amalgamation.

+** 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.
