#
# SYNOPSIS

#
# ::
#
#  $ makenemo
#
#
# DESCRIPTION
# ===========
#
#
# This script aims :
#
# - to choose MYCONFIG
# - to choose compiler options  
# - to create the CONFIG/MYCONFIG/WORK directory
# - to compile this configuration
#
#  Variables used :
#
#  From user input
#
# - NEW_CONF    : configuration to be created
# - REF_CONF    : reference configuration to build the new one 
# - CMP_NAM     : compiler name 
# - NBR_PRC     : number of processes used to compile  
# - NEM_SUBDIR  : NEMO subdirectory used (specified)
#
#  Locally defined :
#
# - TAB         : NEMO subdirectory used (read)  
# - MAIN_DIR    : self explaining
# - CONFIG_DIR  :   "    "    "   
# - MODELES_DIR :   "    "    " 
# - TOOLS_DIR   :   "    "    " 
# - NEMO_DIR    :   "    "    "
