+;;; Commentary:
+;; Cubes are the building blocks of any `FG42' editor.  Each `cube' is a
+;; unit which defines different abilities in a deterministic and idempotent
+;; way.  Cubes are composable and a composition of cubes creates an editor.
+;;
+;;; Code:
+(require 'fpkg)
+(require 'fg42/cube)
+

+(defcube fg42/rust-cube
+  "This cube provides rust support for FG42.
+If the =lsp= flag is set it is going to use the =rust-analyzer=
+as the LSP server so it has to be installed on the host OS.
