Bourbon: like virtualenvwrapper's "workon" but for Rye

I like the Rye project manager better than virtualenvwrapper, but missed workon. So I made a bash shell script that, for my purpose, does the same thing as workon. It's called Bourbon.

When you're in a Rye-based project (for example, project_x), do bourbon add, and then in another terminal session you can do bourbon list to show the projects Bourbon knows about, and bourbon project_x to go to the project. Just type bourbon alone to get help.

To be able to invoke it from anywhere, I put it in my source directory and made it executable with chmod +x bourbon.sh. Then in my .zshrc, I put:

source /Users/garyrob/source/bourbon.sh

If bourbon is too much to type, you can add:

alias bbn=bourbon

The script is at https://github.com/garyrob/bourbon/blob/main/bourbon.sh.
