 Hadrian is a new build system for the [Glasgow Haskell Compiler][ghc]. It is based
 on [Shake][shake] and we hope that it will eventually replace the current
 [`make`-based build system][make]. If you are curious about the rationale behind the

 In addition to standard Shake flags (try `--help`), the build system
 currently supports several others:
-* `--flavour=FLAVOUR`: choose a build flavour. Two settings are currently supported:
-`default` and `quick` (adds `-O0` flag to all GHC invocations and disables library
-profiling, which speeds up builds by 3-4x).

 Current limitations
 -------------------
 The new build system still lacks many important features:
-* We only build `vanilla` and `profiling` way: [#4][dynamic-issue].
+* There is currently no support for the `dynamic` build way: [#4][dynamic-issue].
 * Validation is not implemented: [#187][validation-issue].
 * Only HTML Haddock documentation is supported (use `--haddock` flag). 
-* Build flavours and conventional command line flags are not implemented: [#188][flavours-issue].
+* Not all modes of the old build system are supported, e.g. [#250][freeze-issue].
 * Cross-compilation is not implemented: [#177][cross-compilation-issue].
 * There is no support for installation or binary distribution: [#219][install-issue].
