libghc-syb-with-class-doc binary package in Ubuntu Precise i386

 The "Scrap your boilerplate" approach is a lightweight generic
 programming approach for Haskell. Using this approach, you can write
 generic functions such as traversal schemes (e.g., everywhere and
 everything), as well as generic read, generic show and generic
 equality (i.e., gread, gshow, and geq). This approach is based on
 just a few primitives for type-safe cast and processing constructor
 applications.

 This package contains the library documentation.
