+.B up2date
+This directive should contain a command that prints the current upstream stable
+version of the project. This way we can check for newer version without visiting
+manually the project's website (see above).

hunk ./doc/makepkg.8.in 408
+.B "\-u, \-\-noup2date"
+Do not check for newer version before starting build. Normally makepkg will
+prevent you from building obsolete source by mistake. If you know what you are
+doing, you can disable this feature with this switch.
