Can anyone recommend any useful talks, slides, documents, clones, etc.. of DTrace that would help me get up to speed with how DTrace does what it does so efficiently?

I plan to learn from reading the open source code, but I’d like to at least have some idea of its internal design, before I do.

Apart from a talk by Arun Thomas, can anyone recommend anything? Thanks.

I'm slowly hacking away at a zsh script that shows some promise as a command line tool. I want to learn more about the conventions regarding command line tool development in Unix (and/or macOS), but don't really know where to look for this information.

What is the correct way, or convention, to specify and parse command line arguments, for example? How should I package my tool? What is the best way to handle deployment of the various aspects of my tool, for example the man page, or configuration settings? How should I handle the upgrade process?

Smaller details, like should I store my source code in the repo with execute permissions turned on, or should I only turn on those permissions when the files are deployed on the user's machine? What group should I set as the default for my executable files?

Does anyone know any great resources out there that address these issues?
