-## Note
-
-If you get this error when running the tests, update LuaSocket:
-
-    variable 'PROXY' is not declared
-
-You may need to use the SCM version to run them (see
-[this issue](https://github.com/diegonehab/luasocket/issues/110)).
-
-This only impacts the tests, the code itself works with older versions as well.
