see the file README.cvs (attached) that comes with the PWscf distribution.
CVS tutorial: http://www.loria.fr/~molli/cvs/cvs-tut/ . A few notes on what
can happen when you update:
Update to the latest release: "cvs update"
You should get lines looking like
> cvs server: Updating Modules
> P Modules/Makefile
> U Modules/control_flags.f90
where P means "patched", U means "Updated" (a new file is added); or
> M PW/Makefile
where M means locally modified wrt the CVS repository version; or
> ? CPV/intel.pcl
meaning that cvs knows nothing about such file; or
> cvs server: FPMD/control_flags.f90 is no longer in the repository
meaning that these files are no longer in the repository; but no lines like
> C Somedir/SomeFile
> cvs server: conflict while updating Somedir/SomeFile
This means that somebody else has modified the same parts of the code
that you have locally modified; conflicting files will contain lines like
> something else

The current (development) version is available using anonymous CVS.
Define environmental variables:
setenv CVS_RSH ssh
setenv CVSROOT :pserver:cvsanon at democritos.sissa.it:/home/cvs
export CVSROOT=:pserver:cvsanon at democritos.sissa.it:/home/cvs
(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.
