#
# SYNOPSIS
# ========
#
# ::
#
#  $ correct_terminology.sh [--debug] -good goodend -bad badend -d directory
#
# DESCRIPTION
# ===========
#
# .. option:: --debug
#
#    If this option is set, :samp:`ncdump -v tt` will be added to log file
#
# .. option:: -good goodend
#
#    good end part of the name
#
# .. option:: -bad badend
#
#    bad end part of the name
#
# .. option:: -d <dirin>
#
#    base location of the dataset to be changed
#
# Modify filenames in the dataset based under dirin parameter
#
# Log file is written on :file:`${PROJECT_LOG}/correct_terminology.sh.log.{YYYYMMDDTHHMMSSZ}`
#
#     .. graphviz::
#
#        digraph correct_terminology {
#
#           correct_terminology [shape=box,
#           fontname=Courier,
#           color=blue,
#           URL="http://forge.ipsl.jussieu.fr/tropflux/browser/trunk/src/correct_terminology.sh",
#           label="${PROJECT}/src/correct_terminology.sh"];
#
#           {filein} -> {correct_terminology} -> {fileout}
#
#       }
#
# EXAMPLES
# ========
#
# To modify files under /usr/lodyc/incas/fplod/tropflux_d/to_be_published/ because files are not named
# :file:`var_tropflux_1d_${yyyy}_{yyyy}.nc` but :file:`var_tropflux_1d_{yyyy}_{month}{yyyy}.nc`::
#
#  $ correct_terminology.sh -d /usr/lodyc/incas/fplod/tropflux_d/to_be_published/ -good "1979_2013" -bad "1979_march2013"
#
# And look at log file with ::
#
#  $ tlogd.sh correct_terminology
