Document compatibility with zx2c4's "pass - the standard unix password manager"

[Holzhaus]

Although the command line interface is different, it looks like prs implements the format used by pass. This is not explicitly documented in the README. Is it safe to use for people that switch back and forth, or may modifying the password store using prs lead to a situation where it's not compatible with plain pass anymore? It would be great if that could be documented.

Switching back and forth should be safe! Though my testing on this is somewhat limited.

I do mention compatibility here, but I agree that it isn't really an exhaustive list.

It's special additions that may not work very well with prs together. Tomb support may be a good example, to encrypt your password store directory to prevent metadata leakage. prs handles all of it fully automatically, while pass does not. There are helpers for it though, such as pass-tomb. You could use the very same helper for prs as well, but that's not needed as it will do it for you.
