+baum - an esoteric programming language
+=======================================
+baum is my first try to create an esoteric programming language. It bases on
+the idea to have a tree as source code structure. You should see baum as an
+experiment, it also offers only very restricted possibilities by now.
+
+
+Installation
+------------
+Enter the following command to build and install baum (if necessary as root):
+
+    make clean install
+
+
+Using baum
+----------
+See man page or the examples that are shipped with the program to learn how to
+program in the baum language.
+
+To check you sources run
+
+    baum -c sourcefile.baum
+
+If it exited successful, run the program with
+
+    baum sourcefile.baum
+
+
+
+Feedback
+--------
+Contact me if you are interested in baum. I would like to talk to you :-)
