Overview

This singleton class handles patching for any given library we wish to instrument. To create a new patch for a library, just create a file in the lib/patches directory with any name. These files typically contain code that will monkeypatch a given library. When you wish to execute the code in that file, just call its corresponding patch_ method. For example, if we have a file lib/patches/foo.rb, then we would just call:

::Tracebin::Patches.patch_foo
