INPUT FILE DESCRIPTION

Program: cppp.x / CP / Quantum Espresso (version: 6.6)
------------------------------------------------------------------------


=============================================================================
                            CP Post-Processing code (cppp.x)
=============================================================================

The cppp.x code is an utility that can be used to extract data from the CP
restart and CP trajectory files.

INPUT:
=====

the program read the input parameters from the standard input or from
any other file specified through the usual "-input" command line flag.
The input parameters, in the input file, should be specified in the inputpp
namelist follow:

&INPUTPP
  ...
  cppp_input_parameter
  ...
/
