+********************************************
+** THIS IS NOT THE TEST SUITE FOR LUAJIT! **
+********************************************
+
+In fact it doesn't even have the steps to build it or run it,
+so please don't complain.
+
+This repo is a place to collect and cleanup tests for LuaJIT.
+They should eventually be merged into the main LuaJIT repo.
+
+It's definitely not in the best state and needs a serious
+cleanup effort. Sorry.
+
+
+Many issues need to be resolved before the merge can be performed:
+
+- Choose a portable test runner
+  Requirement: very few dependencies, possibly Lua/Shell only
+
+- Minimal test runner library, wherever assert() is not enough
+
+- Debugging test failures is a lot simpler, when individual tests can still
+  be run from the LuaJIT command line without any big dependencies
+
+- Define consistent grouping of all tests
+
+- Define consistent naming of all tests
+
+- Split everything into a lot of tiny tests
+
+- Reduce time taken to run the test suite
+  Separate tiers, parallelized testing
+
+- Some tests can only run under certain configurations (e.g. FFI)
+
+- Some tests need a clean slate to give reproducible results
+  Most others should be run from the same state for performance resons
+
+- Hard to check that the JIT compiler actually generates the intended code
+  Maybe use a test matching variant of the jit.dump module
+
+- Portability concerns
+
+- Avoiding undefined behavior in tests or ignoring it
+
+- Matrix of architectures + configuration options that need testing
+
+- Merge tests from other sources, e.g. the various Lua test suites.
+
+- Tests should go into the LuaJIT git repo, but in separate tarballs
+  for the releases
+
+
+There are some benchmarks, too:
+
+- Some of the benchmarks can be used as tests (with low scaling)
+  by checksumming their output and comparing against known good results
+
+- Most benchmarks need different scalings to be useful for comparison
+  on all architectures
+
+
+Note from Mike Pall:
+
+I've removed all tests of undeterminable origin or that weren't explicitly
+contributed with the intention of being part of a public test suite.
+
+I hereby put all Lua/LuaJIT tests and benchmarks that I wrote under the
+public domain. I've removed any copyright headers.
+
+If I've forgotten an attribution or you want your contributed test to be
+removed, please open an issue.
+
+There are some benchmarks that bear other copyrights, probably public
+domain, BSD or MIT licensed. If the status cannot be determined, they
+need to be replaced or removed before merging with the LuaJIT repo.
