This allows for having lazy trees at home and finally being able to evaluate huge repos as flakes quickly.

fix: tolerate missing inputs stanza 282cf36bc1

Support not copying the entire source tree to the store 887c8093db

If you want your nixpkgs or other giant repo to evaluate fast, this is
how you have to do it.

Consistently name sources "source" 12330ffb69

This leads to a higher degree of compatibility with CppNix/Lix flakes
since paths now match

test: fully test the no-copy-to-store feature bc8d26d1b9

This ensures that it actually evaluates as expected.

				# Given a source tree containing a 'flake.nix' and 'flake.lock' file,

				# function. It then returns an attrset containing 'defaultNix' (to be used in

				# 'default.nix'), 'shellNix' (to be used in 'shell.nix').

Non-blocking: I've never been super clear on what exactly these attributes contain, and it should probably be documented. Presumably shellNix is devShells.${system}.default, but there's a number of reasonable options for defaultNix...

Not really related to this PR, but seeing this reminded me
