+Now that the Hurd can run (albeit haltingly) on its own, it is
+possible for people who do not have Mach 3.0 single-servers to
+contribute without much trouble.  (However, if you don't have a
+single-server, you probably won't be able to use a debugger, but that
+doesn't mean you can't do debugging, right?)
+
+We at the FSF don't have any expertise in setting up Mach 3.0
+machines; the machines that we do development on belong to the Open
+Software Foundation and were set up by them.  So one of the things on
+the task list is to organize things so that people (like us and most
+of you) who don't know how to do it can do it.  It's not impossible to
+figure out, it's just a pain and a marvelous thing for a volunteer to
+do.
+
+You can get Mach 3.0 from CMU; you get the C library and the Hurd from
+us.  You need the soon-to-be-released version 1.07.6 of the C library
+and the latest Hurd snapshot (as well as our special version of MiG)
+from alpha.gnu.ai.mit.edu.
+
+All our work is based upon i386.  The Hurd (except for a few programs;
+see the Hurd README file) is machine independent.  The C library
+should not be too much trouble to port.  Ports and information about
+porting difficulty for either of these are greatly desired.
+
+The Hurd is not yet self-hosting.  While you are welcome to fetch the
+code and put things together, it is not likely that you will have a
+useful system right now.  But you might be able to do significant work
+(see the task list below).  And, even if you can't do significant
+work, I'm interested in hearing about any places where you had
+particular difficulty.
+
+If you want to start on one of these tasks, please let me know so I
+can keep track of volunteers properly.  This task list will be updated
+periodically; gnu@prep.ai.mit.edu always has the latest version.

+
+GNU Hurd Task List Version 1.0.
+
+If you would like to work on one of these, please contact mib@gnu.ai.mit.edu.
+
+
+Mach 3.0 Work
+
+  o Mach 3.0 comes with CMU makefiles that depend on a drecky environment.  
+  It would be very helpful to have makefiles and installation stuff so
+  that it worked well for cross-compilation between systems and used 
+  GNU tools.
+
+  o MiG needs to be made able to support cross-compilation.
+
+  o A replacement for MiG that understood C .h files.
+
+  o Bootstrap tools and documentation to help people set up Mach 3.0
+  machines if they already have Linux; if they already have Net BSD;
+  if they don't have anything.
+
+  o Mach 3.0 needs to provide support for task virtual timers similar
+  in functionality to the Unix ITIMER_PROF and ITIMER_VIRTUAL timers.
+
+  o Mach 3.0 needs to provide a way for users to do statistical PC
+  profiling similar to the Unix profil system call.
+
+  o Mach 3.0 needs a facility to automatically send task and thread 
+  status on task/thread exit to a port that can only be changed by
+  a privileged user; this would be used to implement process 
+  accounting.
+
+  o Mach 3.0 needs a facility to find out what task is the parent of
+  a given task.
+
+  o Mach 3.0 needs a facility to find out which pages of a task's
+  address space are in core to implement Unix's mincore call.
+
+  o Mach 3.0 needs a facility to do msync.
+
+  o Mach 3.0 needs a replacement for MEMORY_OBJECT_COPY_CALL that 
+  works at least for the cases needed in ordinary files.  (Write mib if
+  you want to know what the problem is and some ideas about how to
+  solve it.)
+
+  o Mach 3.0 needs proxy memory objects.  (mib can tell you what these
+  are and why they are important.)
+
+  o Mach 3.0 needs a way to do per-task resource counters that are
+  accessible to servers called by the task.
+
+  o Mach 3.0 needs facilities to implement resource limits of various sorts.
+
+  o Mach 3.0 needs a way to have a thread's CPU time statistics
+  include time spent by servers on its behalf.
+
+  o Of course, free ports are always necessary to machines that don't
+  already have free ports.
+
+  o Much work can be done doing research in how to improve Mach VM
+  performance and timesharing scheduling policy.
+
+
+Hurd work (these are brief descriptions; mib can give more information):
+
+  o We need a translator for /dev.
+
+  o We need a replacement for utmp and wtmp that understands the
+  Hurd `login collection' concept.  Programs like who and finger
+  then need to be changed to use this.
+
+  o We need some existing shell programs changed to do Hurd things:
+  like ls, su, fsck, tar, cpio, etc.
+
+  o Some new programs need to be written: login, getty, ps, tools
+  for new filesystem features.
+
+  o Shadow directory translators.  (Roland has the beginnings of this.)
+
+  o A system for write, send, talkd and so forth to bleep users;
+  this should be integrated with the utmp replacement above.
+
+  o X.
+
+  o A filesystem for /tmp that uses virtual memory instead of disk.
+
+  o Filesystem implementations (using libdiskfs) for other popular
+  formats, especially the Linux formats as well as MSDOG.
+
+  o Transparent FTP translator.  
+  
+  o NFS client implementation.  You should start with BSD's 4.4 code
+  and support the extensions they support; don't worry about Hurd
+  extensions right now.  (The server we want to write ourselves
+  because it will probably involve changing the Hurd interfaces.)
+
+  o A fancy terminal driver that uses readline and supports detach/attach.
