+The configure script uses autoconf 2.61 and libtool.  If the configure
+script does not work out for you, there is a generic makefile named
+"Makefile.linux-gcc" in the top directory of the source tree that you
+can copy and edit to suit your needs.  Comments on the generic makefile
+show what changes are needed.
+
+The linux binaries on the website are created using the generic makefile,
+not the configure script.  The windows binaries on the website are created
+using MinGW32 configured as a cross-compiler running under Linux.  For 
+details, see the ./publish.sh script at the top-level of the source tree.
+The developers do not use teh configure script.
+
+SQLite does not require TCL to run, but a TCL installation is required
+by the makefiles.  SQLite contains a lot of generated code and TCL is
+used to do much of that code generation.  The makefile also requires
+AWK.
