+# To build a single huge source file holding all of SQLite (or at
+# least the core components - the test harness, shell, and TCL 
+# interface are omitted.) first do
+#
+#      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
+#

+# in this file and extract the version number.  That information will be
+# needed in order to generate the header of the amalgamation.
