>This is the information about an <EM
>installed</EM
> package that
 is communicated to the <TT
>ghc-pkg</TT
> program in order to register
 a package.  <TT
>ghc-pkg</TT
> now consumes this package format (as of version
 6.4). This is specific to GHC at the moment.
</P
><P
>The <TT
>.cabal</TT
> file format is for describing a package that is not yet
 installed. It has a lot of flexibility, like conditionals and dependency
 ranges. As such, that format is not at all suitable for describing a package
 that has already been built and installed. By the time we get to that stage,
 we have resolved all conditionals and resolved dependency version
 constraints to exact versions of dependent packages. So, this module defines
 the <TT
><A HREF="Distribution-InstalledPackageInfo.html#t%3AInstalledPackageInfo"
>InstalledPackageInfo</A
></TT
> data structure that contains all the info we keep
 about an installed package. There is a parser and pretty printer. The
 textual format is rather simpler than the <TT
>.cabal</TT
> format: there are no
 sections, for example.
