Hi Fred, > cabal build pkgname > Build the package named pkgname in the project > cabal build ./pkgfoo > Build the package in the ./pkgfoo directory > cabal build cname > Build the component named cname in the project I think in all these cases the package should be defined in the project file (a single-line project file is enough). Maybe it should say "Build the package mentioned in the project and located in the ./pkgfoo directory"? Cheers, Mikolaj
