# The `srcs` parameter can be used to override the kicad source code
# and all libraries, which are otherwise inaccessible
# to overlays since most of the kicad build expression has been
# refactored into base.nix, most of the library build expressions have
# been refactored into libraries.nix. Overrides are only applied when
# building `kicad-unstable`. The `srcs` parameter has
# no effect for stable `kicad`. `srcs` takes an attribute set in which
# any of the following attributes are meaningful (though none are
# mandatory): "kicad", "kicadVersion", "symbols", "templates",
# "footprints", "packages3d", and "libVersion". "kicadVersion" and
# "libVersion" should be set to a string with the desired value for
# the version attribute in kicad's `mkDerivation` and the version
# attribute in any of the library's `mkDerivation`, respectively.
# "kicad", "symbols", "templates", "footprints", and "packages3d"
# should be set to an appropriate fetcher (e.g. `fetchFromGitLab`).
# So, for example, a possible overlay for kicad is:
#
# final: prev:

# {
#   kicad-unstable = (prev.kicad-unstable.override {
#     srcs = {
#       kicadVersion = "2020-10-08";
#       kicad = prev.fetchFromGitLab {
#         group = "kicad";
#         owner = "code";
#         repo = "kicad";
#         rev = "fd22fe8e374ce71d57e9f683ba996651aa69fa4e";
