This package uses "dub describe" to obtain a list of all dependencies of a D dub project and sets the variable flycheck-dmd-include-paths so that flycheck syntax checking knows how to call the compiler and pass it include flags to find the dependencies If it's not clear what any one function does, consult the unit tests in the tests directory. Usage: (add-hook 'd-mode-hook 'flycheck-dmd-dub-set-include-path)
