If `require("anselme")` fails with an error similar to `module 'anselme' not found`, you might need to redefine `package.path` before the require:
```lua
package.path = "path/?/init.lua;path/?.lua;" .. package.path -- where path is the directory where anselme is located
require("anselme")
```
Anselme expects that `require("anselme.module")` will try loading both `anselme/module/init.lua` and `anselme/module.lua`, which may not be the case without the above code as `package.path`'s default value is system dependent, i.e. not my problem.
