+The prime benchmark
+===================
+
+Bencmarking programming languages by running program to find the first X prime
+numbers. The algorithm is naive and should be implemented the same regardless of
+the language.
+
+Added languages
+---------------
+
+- C
+- Lua
+- PHP
+- Python3
+
+Usage
+-----
+Build: ::
+
+    make
+
+Clean: ::
+
+    make clean
+
+Test: ::
+
+    make test
+
+
+History
+-------
+
+When starting to learn Lua, I wrote a simple program to excersize the table data
+structure. But I had difficulties expressing what I wanted so I first wrote the
+program in Python. After I had the program written in both languages I did the
+obvious thing, I timed them. From there on Barak implemented the program in PHP
+and we implemented it in C. We hope to have many more languages tested.
