+# function zfdir {
+# Long directory of remote server.
+# The remote directory is cached.  In fact, two caches are kept:
+# one of the standard listing of the current directory, i.e. zfdir
+# with no arguments, and another for everything else.
+# To access the appropriate cache, just use zfdir with the same
+# arguments as previously.  zfdir -r will also re-use the `everything
+# else' cache; you can always reuse the current directory cache just
+# with zfdir on its own.
+#
+# The current directory cache is emptied when the directory changes;
+# the other is kept until a new zfdir with a non-empty argument list.
+# Both are removed when the connection is closed.
+#
+# zfdir -f will force the existing cache to be ignored, e.g. if you know
+#          or suspect the directory has changed.
+# zfdir -d will remove both caches without listing anything.
+# If you need to pass -r, -f or -d to the dir itself, use zfdir -- -d etc.;
+# unrecognised options are passed through to dir, but zfdir options must
+# appear first and unmixed with the others.
