+# Lua 5.2.2 Test Suite
+
+This directory contains a modified version of the Lua 5.2.2 test suite. The modifications are primarily to disable or amend some tests 
+so that the test suite can be run. 
+
+## LuaJIT build options
+
+LUA 5.2 compatibility must be turned on.
+
+## Running the test suite
+
+You need to have `luajit` on your path.
+
+On UNIX systems just execute:
+```
+sh run.sh
+```
+
+## Tests disabled or ignored
+Wherever tests have been switched off or ignored a comment has been added and the code has been made conditional. These failures will
+be investigated and either the tests will be modified or permanently disabled depending upon whether the issue is one of compatibility 
+or a defect in LuaJIT. 
+
+Example of excluded test:
+```
+-- FIXME tests fail in LuaJIT
+-- dofile('main.lua')
+```
