Generate an HTML index of installed Haskell packages and their documentation.
docidx is a small tool which creates an HTML index of your installed Haskell packages, with links to each package's Haddock docs locally and on Hackage. While "cabal install" now creates and maintains an index by module, sometimes it's nice to have this other view (and the quick links to Hackage). docidx queries your global and user package databases (via ghc-pkg, via the Cabal package), to build an index of all installed packages - including version numbers where more than one version is present, package synopses, links to the local Haddock docs, and a link to the package on Hackage. Packages are grouped by first letter, and there's an A-Z index at the top of the page, which can be easily extended via a config file to include extra links you think are handy - e.g. to the per-module index, to local ghc documentation, to the Haskell report, etc. - whatever you want).
