NixOS and Home Manager both automatically generate documentation using 'nixosOptionsDoc', and now so does hylonix.
I can't find any standard reference for where this documentation should go, so I have created a doc attribute in the flake.
The pipe operator '<|' was added in Nix 2.24 as experimental. In typical
nix community fashion, an eternity has passed, it's still experimental, and
they're still arguing about it. Thus, in order not to burden any users of
this flake, they have been removed.
To get this done quickly a utility function has been added called 'compose'.
It is 'lib.trivial.pipe' written in reverse. This eliminates any bugs and
performance regressions from unnecessary thunk evaluation.
