  * Add an --only-dependencies flag to "install" (see ticket #697)
  
  This flag installs only the dependencies of the packages that were
  explicitly mentioned on the command line. This is useful for using
  cabal-install in development environments, where the developer needs
  the dependencies to build the package in development, but does not yet
  want to install the package itself.
