• doc - Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
• hscolour - Include coloured haskell sources to generated documentation (dev-haskell/hscolour)
• profile - Add support for software performance analysis (will likely vary from ebuild to ebuild)
• random-initial-seed - Randomly initialize the seed on every executable invocation. This is not a security feature and is intended only for testing (it can affect legitimate use cases).
