/* This file composes a single bootstrapping stage of the Nix Packages
|
|
collection. That is, it imports the functions that build the various
|
|
packages, and calls them with appropriate arguments. The result is a set of
|
|
all the packages in the Nix Packages collection for some particular platform
|
|
for some particular stage.
|
|
|
|
Default arguments are only provided for bootstrapping
|
|
arguments. Normal users should not import this directly but instead
|
|
import `pkgs/default.nix` or `default.nix`. */
