+#!/usr/bin/tclsh
+#
+# Use this script to build C-language source code for a program that uses
+# tclsqlite.c together with custom TCL scripts and/or C extensions for
+# either SQLite or TCL.
+#
+# Usage example:
+#
+#     tclsh mktclsqliteprog.tcl demoapp.c.in >demoapp.c
+#
+# The demoapp.c.in file contains a mixture of C code, TCL script, and
+# processing directives used by mktclsqliteprog.tcl to build the final C-code
+# output file.  Most lines of demoapp.c.in are copied straight through into
+# the output.  The following control directives are recognized:
+#
+# BEGIN_STRING
+#
+#      This marks the beginning of large string literal - usually a TCL
+#      script of some kind.  Subsequent lines of text through the first
+#      line that begins with END_STRING are converted into a C-language
+#      string literal.
+#
+# INCLUDE path
+#
+#      The path argument is the name of a file to be inserted in place of
+#      the INCLUDE line.  The path can begin with $ROOT to signify the
+#      root of the SQLite source tree, or $HOME to signify the directory
+#      that contains the demoapp.c.in input script itself.  If the path does
+#      not begin with either $ROOT or $HOME, then it is interpreted relative
+#      to the current working directory.
+#
+#      If the INCLUDE occurs in the middle of BEGIN_STRING...END_STRING
+#      then all of the text in the input file is converted into C-language
+#      string literals.
+#
+# None of the control directives described above will nest.  Only the
+# top-level input file ("demoapp.c.in" in the example) is interpreted.
+# referenced files are copied verbatim.
+#
