nosetup helps you to load the dependencies of your project into your toplevel of choice (OCaml Toplevel as well as UTOP) so you don't have to #require your dependencies yourself. It does so by finding your project metadata (even if you are in a subdirectory, similar to git), parsing it and then using findlib to load it into your toplevel session.

Currently it supports Merlin's .merlin files, though there is no limitation of which files could be supported as long as the findlib package names can be parsed.
