#
# SYNOPSIS
# ========
#
# Online usage::
#
#  $ . ./project_profile.sh -d directory -i indir -o outdir -t tempdir -s saxo_dir

# DESCRIPTION
# ===========
#
# .. option:: -d  <directory>
# .. option:: -i  <indir>
# .. option:: -o  <outdir>
# .. option:: -t  <tempdir>
# .. option:: -s  <saxo_dir>
#
# define PROJECT environment
#
# ${PROJECT} is the base directory of tools.
#
# ${PROJECT_LOG} is the directory where log files will be written.
#
# ${PROJECT_ID} is the directory where input files must be.
#
# ${PROJECT_OD} is the directory where output files will be written.
#
# PATH is completed with ${PROJECT}/src/.
#
# ${SAXO_DIR} is the base directory of SAXO tools
#
# IDL_STARTUP is set to tell IDL where find tools.
#
# FER_GO is completed with ${PROJECT}/src/.
