This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
An incomplete component of the Hpc toolkit which provides the
ability to step through coverage ticks as they happen, giving a
poor mans debugger. Requires the binary being traced to be build
using a specific version of ghc-6.7, so YMWV.
The plan is to port this to the new GHC API, giving both tracing
and free variable examination via an Ajax interface.
