Otherwise, look for the home page of the package. Usually this is pkgname. If this doesn't work or you don't know the package name, information for all GNU packages is included in the FSF Free Software Directory. The home page should also be prominently mentioned in the package documentation or README files, and is often findable with a general Internet search.
