+#!/usr/bin/tclsh
+#
+# This script constructs the "sqlite3.h" header file from the following
+# sources:
+#
+# 1) The src/sqlite.h.in source file. This is the template for sqlite3.h.
+# 2) The VERSION file containing the current SQLite version number.
+# 3) The manifest file from the fossil SCM. This gives use the date.
+# 4) The manifest.uuid file from the fossil SCM. This gives the SHA1 hash.
+#
+# Run this script by specifying the root directory of the source tree
+# on the command-line.
+#
+# This script performs processing on src/sqlite.h.in. It:
+#
+# 1) Adds SQLITE_EXTERN in front of the declaration of global variables,
+# 2) Adds SQLITE_API in front of the declaration of API functions,
+# 3) Replaces the string --VERS-- with the current library version,
+# formatted as a string (e.g. "3.6.17"), and
+# 4) Replaces the string --VERSION-NUMBER-- with current library version,
+# formatted as an integer (e.g. "3006017").
+# 5) Replaces the string --SOURCE-ID-- with the date and time and sha1
+# hash of the fossil-scm manifest for the source tree.
+#
+# This script outputs to stdout.
+#
+# Example usage:
+#
+# tclsh mksqlite3h.tcl ../sqlite >sqlite3.h
