# pex

I trust that there are many ways a tool could do this, I’m just trying to get a clear picture of how you think it would 🙂 One of the benefits of the approach of “we just add a configurable bootstrap script to the pex file” or similar is that we don’t need to re-design things like “how we actually generate the pex file from a list of source files and requirements”, and I don’t know off the top of my head how many other configuration knobs there are on pex files which we may also need to re-implement the configuration of. My instinct is that we’d just add the entire pex file as a zip entry into the tpex (zip file in a zip file - fun), which avoids needing to do that re-generation at runtime, but maybe you have cleaner ideas?
