New Revision: 256345
URL: http://svnweb.freebsd.org/changeset/base/256345
Log:
Rewrite the keymap module to display an actual menu of selectable
keymaps *and* provide a mechanism for testing the selection. With
this commit, bsdinstall is no longer dependent on kbdmap(1). The
keymap test menu was originally submitted by Warren Block but was
modified).
