+C++ Koans
+
+ABOUT
+=====
+
+Inspired by the Edge Case Ruby Koans ( http://rubykoans.com/ ) 
+I wanted to create something similar for the C++ Language.
+
+The basic idea is to learn a language by unit tests, reading code and
+solving little puzzles filling in resulting values in empty spaces.
+If all expectations are correct, no output is produced, otherwise
+a message is printed.
+
+Of course C++ doesn't lend itself to the approach used in the 
+ruby koans, making heavy use of reflection and the dynamic aspects
+of the ruby language. Also, I wanted a single place to put notes 
+about language and syntax specifics, to be able to look it up quickly. 
+
+Therefore, the C++ Koans are much more simple in structure and contain
+basic content as well (as, e.g., control structures which are not at all
+surprising). Also, I skipped the whole reflection part. There is a main
+that calls all the meditate functions of all Koan classes, and all single 
+Koans in a class are called via this function. To check that I haven't 
+forgotten anything there's a little ruby script scripts/check_all_called.rb
+which does exactly that. Although this simple structure might not be as
+elegant as the ruby Koans or even as it could be within C++, I preferred it
+as it is easy understandable by a C++ beginner.
+
+USAGE
+=====
+
+Just check out the master branch, run CPPKoans.cpp and start filling out the 
+empty spaces ( marked with _____ ) with the correct values. You can choose
+if all koans should be run or if the program should terminate at the first
+unmet expectation by setting QUIT_ON_UNMET_EXPECTATION in StopMeditating.h.
+If you want to change the order of the koans or just pick
+some, rearrange or comment them out in the main function.
+
+ADDING NEW KOANS
+================
+There are two branches in the repository: master and development. 
+The master branch contains the empty spaces to fill in, the development branch
+contains the solutions. If you add koans, it is easier to do so in the development 
+branch, merge the changes to master and then run scripts/replace_expectations.rb
+to replace the values with the _____ placeholder.
+
+If you want to help develop them further, feel free to contact me at
+kleinen@infrastructure.de or send me a pull request.
