Support for multiple profiles undocumented

[rjc]

Hello,

I've noticed that support for multiple profiles (PR #93) has been merged in commit d4453cb44a10f9bb558fd2a5561cc5223ba36a23 but how to use it isn't actually documented anywhere, i.e. not even mentioned in the README.

Even the commit messages itself isn't clear whether RBW_PROFILE environment variable is a path in the sense of a directory containing config.json, or whether it is simply a file name, etc. It also isn't clear whether this should be an absolute or relative path.

The way I'd see it is like this, for:

$ RBW_PROFILE=foo rbw list

I'd search for a file called foo.json in:

$HOME/Library/Application Support/rbw

on macOS, or:

$HOME/.config/rbw

on other *nix OSes.

@rjc Thank you for mentioning that PR, I was just installing rbw and this came useful!

I'm not fluent in Rust, but from a cursory read, what changes is whether it should use

• <config_base_path>/rbw/config.json (default in the case RBW_PROFILE is undefined)
• <config_base_path>/rbw-${RBW_PROFILE}/config.json

(<config_base_path> being defined in directories::ProjectDirs.config_dir() depending on the platform)

In my case (Linux):

RBW_PROFILE=work rbw config show
... $XDG_CONFIG_HOME/rbw-work/config.json contents ...
