+# Usage:
+#	require "finddepth.pl";
+#
+#	&finddepth('/foo','/bar');
+#
+#	sub wanted { ... }
+#		where wanted does whatever you want.  $dir contains the
+#		current directory name, and $_ the current filename within
+#		that directory.  $name contains "$dir/$_".  You are cd'ed
+#		to $dir when the function is called.  The function may
+#		set $prune to prune the tree.
+#
+# This library is primarily for find2perl, which, when fed
+#
+#   find2perl / -name .nfs\* -mtime +7 -exec rm -f {} \; -o -fstype nfs -prune
+#
+# spits out something like this
+#
+#	sub wanted {
+#	    /^\.nfs.*$/ &&
+#	    (($dev,$ino,$mode,$nlink,$uid,$gid) = lstat($_)) &&
+#	    int(-M _) > 7 &&
+#	    unlink($_)
+#	    ||
+#	    ($nlink || (($dev,$ino,$mode,$nlink,$uid,$gid) = lstat($_))) &&
+#	    $dev < 0 &&
+#	    ($prune = 1);
