+# This script builds a single C code file holding all of FTS2 code. |
+# The name of the output file is fts2amal.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 mkfts2amal.tcl |
+# |
+# The amalgamated FTS2 code will be written into fts2amal.c |
+# |
+ |
+# Open the output file and write a header comment at the beginning |
+# of the file. |
+# |
