#
# SYNOPSIS
# ========
#
# ::
#
#  $ tropflux.sh -b yyyymmdd -e yyyymmdd
#
# DESCRIPTION
# ===========
#
# Run all needed :file:`*.pro` to create the TropFlux dataset between two dates
#
# We suppose here that all inputs data are already available localy.
#
# .. option:: -b beginning date <yyyymmdd>
# .. option:: -e end date <yyyymmdd>
#
# Some IDL programs are launched here using ${IDL_CMD} command
# (see :ref:`project_profile.sh` to know how to set this environnement variable).
#
# Log file is written on
# :file:`${PROJECT_LOG}/tropflux.log.{YYYYMMDDTHHMMSSZ}`
#
# .. only:: man
#
#    Figure is visible on PDF and HTML documents only.
#
# .. only:: html or latex
#
#     .. graphviz::
#
#        digraph tropflux {
#
#           file_oaflux [shape=ellipse,fontname=Courier,label="${PROJECT_ID}/lh_oaflux_2004.nc"];

#           log [shape=ellipse,fontname=Courier,label="${PROJECT_LOG}/tropflux.log{YYYYMMDDTHHMMSSZ}"];
#
#           tropflux [shape=box,
#           fontname=Courier,
#           color=blue,
#           URL="http://forge.ipsl.jussieu.fr/tropflux/browser/trunk/src/tropflux.sh",
#           label="${PROJECT}/src/tropflux.sh"];
#
#           {file_oaflux} -> {tropflux} -> {log fileout}
#
#         }
#
# EXAMPLES
# ========
#
# You already used :ref:`get_erai.sh` to get ERAI data, etc.,
# during [20000101, 20000302[ and you want to produce NetCDF files::
#
#   $ tropflux.sh -b 20000101 -e 20000302
#
# A more global example::
#
#   $ tropflux.sh -b 19890101 -e 20091231
#
# And look at log file with ::
#
#  $ tlogd.sh tropflux
#
# and of course on files in ${PROJECT_ID}.
