when a calculation was restarted wfc were always read by file
(no matter whether the startingwfc keyword was set or not).
The same was true for the potential.

- basic cell and ionic variables moved frpm pwcom to
cell_base and ions_base .
cell_base modules and ions_base modules should be initialized
through the use of cell_base_init and ions_base_init, this after
having read the namelists and the cards .
IN THE FUTURE NONE OF THE VARIABLES IN THE BASIC MODULES SHOULD
BE SET IN THE MAIN CODES, BUT THROUGH A CALL TO SOME INIT
FUNCTIONS CONTAINED IN THE BASIC MODULE ITSELF.
THE IDEA IS THAT THE BASIC VARIABLES SHOULD BE USED AS
READ-ONLY. UNFORTUNATELY IN F90 THERE IS NO POSSIBILITY
TO SET A READ ONLY ATTRIBUTE.

Molecular Dynamics based algorithm partially rewritten:
both standard and damped MD are performed with the velocity Verlet
scheme (with or without constrains).
Renata's subroutines are used only in the framework of variable
cell.
constrain.f90 file is no longer needed: cnstrains are set in the
input file (see CONSTRAINTS CARD) with the same input format used
in FPMD. An arbitrary number of constrains can be set.
In the case of constrained relaxation the damped MD
algorithm is used instead of BFGS.
When restart_mode = "from_scratch" many reastr files are removed
from the scratch directory.
Several other modifications here and there. (C.S.)

correct place (kinds); module "varie" replaced by "control_flags" (not
yet in pwcom, though) - many many files changed.
64-bit cpus (Opteron, maybe Itanium) should now work if __LINUX64 is defined

This value of ethr is overwritten (with a warning message) in the case of a phonon calculation (lphonon flag added). If diago_thr_init is not specified in the input file it is automatically set in setup.f90 (for example in the case of a nscf calculation ethr = tr2 / nelec).
I hope this policy is appropriate for all kind of calculations.

From now on, all file names and their unit and attributes (i.e. reclen)

"Total force" now prints a more sensible quantity:
\sqrt(\sum_{i,n} f_i(n)^2) instead of \sum_{i,n} |f_i(n)|

From now on, all new input variables should be added
to this module, and then copied to the code internal
variables in the input.f90 subroutine
The namelists and cards parsers are in :
Modules/read_namelists.f90 and Modules/read_cards.f90
files input_parameters.f90 read_namelists.f90 read_cards.f90
are shared by all codes, while each code has its own version
of input.f90 ( used to copy input values into internals variables ).
EXAMPLE:
suppose you need to add a new input variable called "pippo"
to the namelist control, then:
1) add pippo to the input_parameters.f90 file containing the
namelist control
INTEGER :: pippo = 0
NAMELIST / control / ....., pippo
remember: always set an initialization value!
2) add pippo to the control_default subroutine
( cantained in module read_namelists.f90 )
subroutine control_default( prog )
...
IF( prog == 'PW' ) pippo = 10
...
end subroutine
this routine set the default value for pippo,
that could vary with the code
3) add pippo to the control_bcast subroutine
( cantained in module read_namelists.f90 )
subroutine control_bcast( )
...
call mp_bcast( pippo )
...
end subroutine
4) add pippo to the control_checkin subroutine
( cantained in module read_namelists.f90 )
subroutine control_checking( prog )
...
IF( pippo < 0 ) &
CALL error(' control_checkin ',' variable pippo less than 0 ', 1 )
...
end subroutine
5) Copy the value of pippo in the code internal variables
( file input.f90 )
subroutine iosys()
use input_parameters, only: ...., pippo
use pwcom, only: ....., myvar
...
call read_namelists( 'PW' )
...
myvar = pippo
...
end subroutine
