This was briefly mentioned in #3.
Proposal
It would be handy to have an option for automatic installation of packages in venvlinkrc, like install_packages or autoinstall_packages. This could be a list, like [numpy, matplotlib].
Versions could be defined as defined in PEP440; numpy~=1.19.5 for numpy versions 1.19.x but greater or equal than 1.19.5.
Example (venvlinkrc):
autoinstall_packages = [numpy~=1.19.5, matplotlib]
