The idea of "nail" package was to include into Fedora the newest implementation of the ancient /bin/mail command -- by "Heirloom mailx" project. The name of "nail" was chosen to not conflict with the existed mailx-8.x ("Nail" was an initial name of Heirloom mailx).

Since Fedora 10, the old mailx-8.x is replaced with Herloom mailx. Thus no more need for "nail" package (it is now the same as the ordinary mailx).

All "Obsoletes:" etc. are done as usual.

Please, drop "nail" from the upcoming F10 and rawhide.
