Hi Joachim,
that's right thanks, but I was looking for a way to do that from a program.
ghc-pkg does not seems to expose any library...

I'm looking for how to extract the exposed modules (as a list of
strings) from an installed library, giving the library name.
I can see some structures in Cabal (InstalledPackageInfo) and some
functions in ghc-pkg.hs in GHC, but nothing readily useable... $ ghc-pkg field base exposed-modules
