Dear developers:
There are three trivial slip of example22.

In the "README" file of example22:
ONE: "2) make a band structure calculation for Pt (input=pt.band.in,
output=pt.band.out)."
should be "(input=pt.nscf.in,   output=pt.nscf.out)."
TWO:"9) make a self-consistent calculation for Pt in a tetragonal cell with
4 atoms  (input=pt.tet4.in, output=pt.tet4.out)."
should be " (input=pt4.in, output=pt4.out)."

THREE: When I try to open "pt.nscf_ph.in" with PWgui, I get the follow
error"syntax error in the input file:expecting keyword ATOMIC SPECIES, but
read PHONON instead"
I use espresso4.0.4. But I notice that in espresso4.1, there is not "
pt.nscf_ph.in" file any more.
The "pt.nscf_ph.in" is given below:
"Pt
Pt
 &control
    calculation = 'phonon'
    restart_mode='from_scratch',
    prefix='Pt',
    pseudo_dir = '/home/raman/espresso-4.0.4/pseudo/',
    outdir='/home/raman/tmp/'
