The current (development) version is available using anonymous CVS. 
Define environmental variables:
   setenv CVS_RSH ssh
   setenv CVSROOT :pserver:cvsanon@democritos.sissa.it:/home/cvs
(tcsh/csh) or
   export CVS_RSH=ssh
   export CVSROOT=:pserver:cvsanon@democritos.sissa.it:/home/cvs
(sh/bash). Then:
   cvs login
(password: cvsanon). For the first code download:
   cvs co O-sesame
for the entire repository (the code appears in directory O-sesame/).
Alternatively, "cvs co pwscf", or "cp", or "fpmd" will download only
PWscf, CP, FPMD, respectively, in directories with the same name.
For updating the code to the current version:
   cvs update -d
in the directory containing the distribution.

PLEASE NOTE: re-run "./configure" if files have been moved/added/removed
since the last checkout, otherwise "make" may not work properly due to
obsolete or missing dependencies. Do not blindly re-use a "make.sys" file
from a preceding version: it may no longer work.

PLEASE ALSO NOTE: the development version may not work properly, and
sometimes not even compile properly. Use at your own risk.
