[TxMt] run/compile from any file in project?

[Christopher Brewster]

With the latex bundle, I can put a %!TEX root = directive in each file, or esle use TM_LATEX_MASTER so whichever file I am editing, I can still compile the whole document.

How do I do this in other contexts, e.g. with a python project?

(I have tried search engines but could not come up with the right query to find the answer).

Thanks,
Christopher
