+# This script builds a single C code file holding all of FTS3 code.
+# The name of the output file is fts3amal.c.  To build this file,
+# 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.)
+#
+# After the "tsrc" directory has been created and populated, run
+# this script:
+#
+#      tclsh mkfts3amal.tcl
+#
+# The amalgamated FTS3 code will be written into fts3amal.c
+#
+
+# Open the output file and write a header comment at the beginning
+# of the file.
+#
+set out [open fts3amal.c w]
