Directory based environment variable scope - how to implement?

Question

I have a set of tools which I need to pass parameters depending on the project I\'m working on. I\'d like to be able to automatically set a couple of environment variables based

This is not pretty, but you can use a combination of exported environment variables and the value of $PWD.

For example:

export VAR1=prefix
export prefix${HOME////_}_foo=42
export prefix${HOME////_}_bar=blah

Then myscript needs only to eval echo \${$VAR1${PWD////_}} to get at the directory based value.
