# DESCRIPTION
# ===========
#
# replace <element>ginette</element> by a sequence like with element given
# in argument <a href="./ginette.html">ginette</a>
# in all html files in dirhtml given in argument
# We have to deal with the path of ginette.html in refhtml also given in
# argument.
#
# see call in savesaxo.sh

# add -e (element) parameter to define element syntax like
# <pro></pro> or <proidl>...</proidl>
# add -i parameter : this directory is the one where we are looking for
# html files to be modified. so replace output by dirhtml
# add -r parameter :  this directory is the one where we are looking for
# html files to be linked
# remove lowercase translation (because of idl help files which are in
# uppercase)

# correction from
# 4.11. How do I match only the first occurrence of a pattern?
# in sed faq http://www.student.northpark.edu/pemente/sed/sedfaq4.html#s4.11
#++ still not working perfectly because path of links on the different occurences of <pro>...</pro> may not be the same
# ex: see restoreboxparam.pro : domdef and saveboxparam
# fplod 2007-06-26T13:32:06Z aedon.locean-ipsl.upmc.fr (Darwin)
# improvment for multiple occurences of <pro>...</pro> on one line
# see http://www.gentoo.org/doc/en/articles/l-sed2.xml

# especially for directory-overview files
