RFE: packagize the metaconfiguration script

[mgedmin]

Every now and then I want to run the script to update a package, and then I realize that I can't just cd zope.sendmail && run something, I have to juggle two working directories somehow, and then I give up.

I'd like to be able to pipx install -e ~/src/zopefoundation/meta and have a runnable zope-meta (better name suggestions welcome) script in my PATH.

TBH a simple wrapper script I could put in ~/bin/ would suffice for me, as long as I can cd ~/src/zopefoundation/something and run zope-meta --help

[mgedmin]

So I tried a wrapper like this:

#!/bin/sh
# Workaround for https://github.com/zopefoundation/meta/issues/97
config_base=$HOME/src/zopefoundation/meta/config
if ! test -x "$config_base"/bin/python; then
    (cd "$config_base" && python3 -m venv .)
    "$config_base"/bin/pip install -r "$config_base"/requirements.txt
fi
"$config_base"/bin/python "$config_base"/config-package.py "$@"

and running cd ~/src/zopefoundation/zope.interface && zope-meta . makes config-package.py think the package name is an empty string, with sad results.
