+     The \cb{pkg-update} command updates the previously configured (via
+     \l{bpkg-pkg-build(1)} or \l{bpkg-pkg-configure(1)}) package. Underneath,
+     this command doesn't do much more than run \cb{b update}.
+
+     Additional command line variables (<vars>, normally \cb{config.*}) can be
+     passed to the build system by either specifying them before the packages,
+     in which case they apply to all of them, or after a specific package, in
+     which case they apply only to this package."
