able to have scripting for default, and avoid external dependences.

+HOW BIG IS IT?
+--------------------------------------------------------------------------------
+
+Jim compiled with -Os is 65k currently. Still it lacks core commands
+that will make it a little bigger, but not too much... only what's
+strictly required will end inside the core, the rest will be implemented
+as extensions.
+
+Note that the actual Jim core is much smaller, if you strip away commands.
+If you can do without [expr] (that's big about code size), and some
+other command you may probably end with a 40k executable.
+
+--------------------------------------------------------------------------------
+HOW FAST IS IT?
+--------------------------------------------------------------------------------
+
+Jim is in most code faster than Tcl7.6p2 (latest 7.x version),
+and slower than Tcl 8.4.x. You can expect pretty decent performances
+for such a little interpreter.
+
+If you want a more precise measure, there is 'bench.tcl' inside this
+distribution that will run both under Jim and Tcl, so just execute
+it with both the interpreters and see what you get :)
