FreeVMS project was created a long time ago. First kernels (until 0.3) 
were derivated from Linux kernel (2.4.15 if I remember) and were 
monolithic. These kernels were bootable but not easely maintenable.

0.4 is rewritten from scratch on a L4 (like Hurd is written on a Mach 
kernel or MacOS X on NVU). L4 is choosen because it deos not contains 
unixism. It boots, it contains first memory management subroutines, but 
pager is missing.

Now, FreeVMS is slepping because there is no developers. To be alive, 
this project need :
- a pager ;
- some drivers (disk I/O), filesystems... Some code have been written 
(ODS2/5 for example) for O.3 kernel ;
- a swapper ;
- some libraries (a real POSIX libc et VMS libraries) ;
- some contributers to write documentation and write pages on 
www.freevms.net.

Goal of FreeVMS is to propose a clone of OpenVMS with a good POSIX 
subsystem. Microkernel (L4) is written in C++ and servers written over 
L4 are written in procedural C++ too. First arch is amd64.
