+Although there is no standard (POSIX or other) for the layout of the `/proc`
+pseudo-filesystem, it turned out a very useful facility in GNU/Linux and other
+systems, and many tools concerned with process management use it. (`ps`, `top`,
+`htop`, `gtop`, `killall`, `pkill`, ...)
+
+Instead of porting all these tools to use [[libps]] (Hurd's official method for
+accessing process information), they could be made to run out of the box, by
+implementing a Linux-compatible `/proc` filesystem for the Hurd.
+
+The goal is to implement all `/proc` functionality needed for the various process
+management tools to work. (On Linux, the `/proc` filesystem is used also for
+debugging purposes; but this is highly system-specific anyways, so there is
+probably no point in trying to duplicate this functionality as well...)
+
+*Status*: Madhusudan.C.S has implemented a new, fully functional [[procfs|madhusudancs]] for
+[[GSoC 2008|community/gsoc/2008]].
+
+In August 2010, Jérémie Koenig [published another, new
+version](http://lists.gnu.org/archive/html/bug-hurd/2010-08/msg00165.html).
