installFonts: init hook

# shellcheck shell=bash

# Setup hook that installs font files to their respective locations.

#

# Example usage in a derivation:

#

#   { …, installFonts, … }:

#

#   stdenvNoCC.mkDerivation {

#     …

#     outputs = [

#       "out"

#       "webfont" # If .woff or .woff2 output is desired

#     ];

#

#     nativeBuildInputs = [ installFonts ];

#     …

#   }

#

# This hook also provides an `installFont` function that can be used to install

# additional fonts of a particular extension into their respective folder.
