+III.
+
+The have() function is used to conserve memory by only installing completion
+functions for binaries actually present on your system. The current method of
+determining whether or not a binary is present is whether or not it is in your
+$PATH.
+
+This approach has the disadvantage that sudo completion will not be able to
+perform sub-completion on, say, ifconfig if /sbin is not in your path, which,
+as an unprivileged user, it typically isn't.
+
+The work-around for this is to put all directories of binaries for which you
+require completion into your $PATH variable.
