#    install.sh -w dirwww -p dirpublish -u urlpublish -l login
#
# DESCRIPTION
# ===========
#
# publication (rsync) of dirwww content on dirpublish given in argument
#
# If the host of publication is cerbere.locean-ipsl.upmc.fr, a specific update

# .. option:: -w  <input directory>
# .. option:: -p  <output directory>
# .. option:: -u  <output url>

#
# If needed, existing directories might be removed before (to erase obsolete
# files), using :command:`ncftp` tool :
#
# For example, to clean directory on LOCEAN web server:
#
# .. code-block:: sh
#
#    ncftp -u fplod www.locean-ipsl.upmc.fr
#    ncftp> cd fplod
#    ncftp> rm -f pageperso/.DS_Store
#    ncftp> rm -rf pageperso
#    ncftp> exit
