{ lib, pkgs, depot, ... }:
# Takes a derivation and a list of binary names
# and returns an attribute set of `name -> path`.
# The list can also contain renames in the form of
# `{ use, as }`, which goes `as -> usePath`.
#
# It is usually used to construct an attrset `bins`
# containing all the binaries required in a file,
# similar to a simple import system.
#
# Example:
#
# bins = getBins pkgs.hello [ "hello" ]
# // getBins pkgs.coreutils [ "printf" "ln" "echo" ]
# // getBins pkgs.execline
# [ { use = "if"; as = "execlineIf" } ]
# // getBins pkgs.s6-portable-utils
# [ { use = "s6-test"; as = "test" }
# { use = "s6-cat"; as = "cat" }
# ];
#
# provides
# bins.{hello,printf,ln,echo,execlineIf,test,cat}
#
