+Jim examples
+============
+BSD 2-clause license, (c) 2010 Wojciech A. Koszek <wkoszek@FreeBSD.org>
+
+
+This directory contains examples of Jim interpreter API. In order to start
+working with Jim API one may just want to copy existing example .c file
+into new file, modify Makefile and start working on a new program.
+
+Existing examples
+=================
+
+jim_command
+	Simple command implementation in Jim's API. Command is then executed
+	in a script encoded within a program.
+
+jim_hello
+	Standard "Hello world!" program.
+
+jim_inline
+	Similar "Hello world!" program, but the result comes from a Tcl
+	script interpreted in Jim. Result is printed back on a terminal.
+
+jim_list
+	Will teach you how to create a list in Jim's API.  Once created,
+	will show how to name and export it, so that variable is visible in
+	the script's source code. Once done, interpretation of separate
+	print.tcl file is presented. As a result, the script can print a
+	list members created from within ANSI C program.
+
+jim_obj
+	Basic object creation in Jim.
+
+jim_return
+	Similar to jim_command example, but implemented command actually
+	returns a value.
