+; Sample usage of TinyScheme Extension
+; This simple program lists the directory entries on the
+; user's home directory.
+
+; It uses the following TinyScheme Extension functions:
+;    getenv
+;      Used to get HOME environment variable.
+;    open-dir-stream
+;      Used to open directory stream.
+;    read-dir-entry
+;      Used to read directory entries.
+;    close-dir-entry
+;      Used at the end, to close directory stream when done.
+
+; check that extensions are enabled
+(if (not (defined? 'load-extension))
+    (begin
+      (display "TinyScheme has extensions disabled. Enable them!!")
+      (newline)
+      (quit)))
+
+; load TinyScheme extension
+(load-extension "tsx-1.1/tsx")
