# PSEUDO_DIR = path of pseudopotentials required by the examples

# example scripts will try to download them from NETWORK_PSEUDO
# TMP_DIR = temporary directory to be used by the examples
# Make sure that it is writable by you and that it doesn't contain
# any valuable data (EVERYTHING THERE WILL BE DESTROYED)
# The following should be good for most cases

# To run the ESPRESSO programs on a parallel machine, you may have to
# add the appropriate commands (poe, mpirun, mpprun...) and/or options
# (specifying number of processors, pools...) before and after the
# executable's name. That depends on how your machine is configured.
# For example on an IBM SP4:
#
# poe pw.x -procs 4 < file.in > file.out
# ^^^ PARA_PREFIX ^^^^^^^^ PARA_POSTFIX
#
# To run on a single processor, you can usually leave them empty.
# BEWARE: most tests and examples are devised to be run serially or on
# a small number of processors; do not use tests and examples to benchmark
# parallelism, do not run on too many processors
