line argument "-ntask_groups" to specify the
number of task group used in parallelization.
to generate an executable with BGL extensions,
in the file make.sys the macro __BGL should
be specified.

This allowes for the possibility of setting constraints that are not collective
variables. Example and documentation updated.

all the scf engines)
- Clean-ups

density file is not written (perhaps the default could be reverted)
2) added an option ion_velocities='change_step'. Here one restarts from
a file with CG while changing the timestep. The old timestep should be supplied
in tolp. The main goal is to make the [t-1] ion positions to be proportionally
smaller. This way one can go through CP->CG->CP sequence while changing the
timestep and keeping all the ionic and Nose positions & velocities fully
consistent as to keep previous equilibration. Perhaps variable cell variables
should also be rescaled in the same way.
Option 2) is somewhat ugly in how things are specified, but practically useful
if one does not want to re-equilibrate with the time step change.
I could not extract the timestep value from the restart file, is it not
being written?

dynamics is automatically done if the CONSTRAINTS card is present. Added a keyword to
monitor the value of the constraints during the simulation. In this case the constraints are
not imposed.

- Many ortho auxiliary functions (tauset, rhoset, sigset, calphi, updatc)
are now in common between FPMD/CP, and moved to module ortho_base.f90
- In FPMD, three index vectors, related to real space like charge and potential
have been substituted with single index vector like in CP, for compatibility
and efficiency.

However in systems containing many atoms of various kinds it can help reduce
human errors. If unspecified, this parameter is ignored. [silviu]

The idea is that module funct contains data defining the DFT functional in use
and a number of functions and subroutines to manage them.
Data are PRIVATE and are (shuold be) accessed and set only by function calls.
Basic drivers to compute XC quantities are also included.
It should be the main place where definitions for and calculation of xc
functionals are centralized.

NEB: removed unused variables; removed allocatable input arrays from input_parameters (to be
consistent with the rest of the input stuff) and replaced by static arrays.
XML: unit 99 used to read/write wfc's replaced by a call to iotk_free_unit.
constraints: the static array "fion" is passed as an array-section to constraint subroutines.
metadyn: fe_step must be defined as an array of "time-steps" (one for each deg-of-freedom).

- Changes in stdout: relevant physical quantities ( positions velocities an cell )
are now printed with the seme format of the corresponding input card,
like in PW, as was suggested by SdG.
- exemple23 updated to reflect the new input namelist "wannier"
- Subroutine init_run now is used in FPMD too.
- WARNING in the stress computed with CP, for a pseudo with core-corrections,
a contribution is missing! Not yet fixed, I need to talk with PG for the

This patch adds "massive" Nose-Hoover chains for ions (i.e. each ion
can have a separate NH chain attached to it)
Some fixes are still needed in different places:
-the information on the number of NH chains [nhpdim] needs to be
saved and read from the restart file (not done now)
-the NH velocities also need to be all saved [nhpdim*nhpcl]
-an input option needs to be added to zero out the NH velocities during
a restart in order to permit "on the fly" thermostat changes
-deallocation of the module variables gives glibc error with IFC 8.0 & 8.1 in
