the help pages were completely translated into the Scilab 5 DocBook format.
Thanks to bugfixes to Scilab 5.1.1. the xmltodocbook toolbox now
worked just fine in converting the old Scilab 4 xml files to the new
ones. It seems the Scilab team has been pretty active, they respond to
my bug reports sooner or later.
SIP 0.4.1 should be out soon with these improvements and other minor fixes.
