+Tests for vis - a vim-like editor frontend
+------------------------------------------
+
+The basic idea is to feed the same keyboard input to both vim
+and vis and compare their respective results.
+
+A test constitutes of 2 files:
+
+ * `test.in` the file/buffer content with which the editor is started
+ * `test.keys` a file containing the keyboard input as would normally
+   be typed by a user
+
+The toplevel shell script `test.sh` looks for these files in subdirectories,
+executes both editors and compares the resulting output.
+
+Type `make` to run all tests.
