+This information is gathered to help design the new built-in
+backend for sqlite 2.0. Note in particular that 99% of all
+database entries have a combined key and data size of less than
+144 bytes. So if a leaf node in the new database is able to
+store 144 bytes of combined key and data, only 1% of the leaves
+will require overflow pages. Furthermore, note that no key
+is larger than 99 bytes, so if the key will never be on an
+overflow page.
+
+The average combined size of key+data is 48. Add in 16 bytes of
+overhead for a total of 64. That means that a 1K page will
+store (on average) about 16 entries.

+How To Build A Dynamically Loaded Tcl Extension
+
}
+puts {
+This note was contributed by
+Bill Saunders. Thanks, Bill!
+
+
+To compile the SQLite Tcl extension into a dynamically loaded module
+I did the following:
+
+
+
+Do a standard compile
+(I had a dir called bld at the same level as sqlite ie
+ /root/bld
+ /root/sqlite
+I followed the directions and did a standard build in the bld
+directory)
+Now do the following in the bld directory
+
+gcc -shared -I. -lgdbm ../sqlite/src/tclsqlite.c libsqlite.a -o sqlite.so
+
+This should produce the file sqlite.so in the bld directory
+Create a pkgIndex.tcl file that contains this line
+
+
+package ifneeded sqlite 1.0 [list load [file join $dir sqlite.so]]
+
+To use this put sqlite.so and pkgIndex.tcl in the same directory
+From that directory start wish
+Execute the following tcl command (tells tcl where to fine loadable
+modules)
+
+lappend auto_path [exec pwd]
+
+Load the package
+
+package require sqlite
+
+Have fun....
