#
# SYNOPSIS
# ========
#
# Online usage
#
# .. code-block:: bash
#
#    . geomag_profile.sh -d directory -i indir -o outdir -t tempdir
#
# In :file:`${HOME}/.profile`, add the following line:
#
# .. code-block:: bash

# DESCRIPTION
# ===========
#
# .. option:: -d <directory>
# .. option:: -i <indir>
# .. option:: -o <outdir>
# .. option:: -t <tempdir>
#
# define GEOMAG environment
#
# ${GEOMAG} is the base directory of tools.
#
# ${GEOMAG_LOG} is the directory where log files will be written.
#
# ${GEOMAG_ID} is the directory where input files must be.
#
# ${GEOMAG_OD} is the directory where output files will be written.
#
# MANPATH++
#
# EXAMPLES
# ========
#
# For fplod, on aedon.locean-ipsl.upmc.fr:
#
# .. code-block:: bash
#
#    cd /usr/home/fplod/incas/geomag/geomag_ws
#    . geomag_profile.sh -d /usr/home/fplod/incas/geomag/geomag_ws/ -i ${HOME}/geomag_d/ -o ${HOME}/geomag_d/ -t /usr/temp/${LOGNAME}/log/
