# Author : Alain Castera <castera@in2p3.fr>
# Modifies only some things from letter.layout
# to use the lettre.cls class from Denis Megevand
# (almost) nothing regarding fax, only letter
#---------------
# rev 1; A. Castera :
# A lot of LateX code added to avoid being bored by
# the imposed command order of the class letter (see comments)
#---------------
#rev 2; A. Castera :
# further more LaTeX code to make tth happy
# with the class.(Following a request on 
# such kind of thing from lyx-users@lists.lyx.org)
#---------------
# rev.3; J.-P. Chretien oct 2010
# general update and review for inclusion in lyx-1.6.8
#  - remove tth stuff
#  - english named styles (translated in fr.po)
#  - margins set to dynamic to ensure alignment of line headings
#  - categories
#  - ordering control left at the beginning (any other way ?)
