Provide utility environment variables to `meta-exec`

🚀 Feature Proposal

Have things like current folder name (just the name, not the full path) as an environment variable you can use in commands

Motivation

Take this for example. I have three repos (two python repos & one node)

And I run the following command:

$ meta exec "[ -f requirements.txt ] && echo dir:`pwd`" --include-only=python-project-1,python-project-2,node-project-2

The context or current working directory is still where I ran the command from. It would be good to have access to such things when running meta-exec. But I don’t know if this should be in loop or meta-exec. An environment variable like META_CWD. See example below.

Example

Say I want to create virtual environments for all my python projects with just the folder name as the venv name.

$ meta exec "[ -f requirements.txt ] && python3 -m venv --prompt $META_CWD   .venv"

Currently there is no easy way to do this so I just manually create my virtual environments. Hope I am making sense.
