[Nix-dev] Creating dependency trees.

[stewart mackenzie]

Dear nixers,

I have a file which contains only

in => a nand(maths_boolean_nand) out => out
in => b nand()

maths_boolean_nand is a derivation name.

I need to essentially do this:

substituteInPlace lib/lib.subnet \
--replace "(" "(${" \
--replace ")" "})"

So that nix can build a dependency tree for me!

Please advise, as I cannot get the ${ substitution to work.

thanks!
