#-------------------------------------------------------------------------
# generates an xsl stylesheet containing a template for special
# cases in the book:
#  - If the version does not begin with a number, it is impossible to know
#    where the package name ends and where the version begins. We therefore
#    use the ENTITY at the beginning of the validated full-xml.
#  - If a package is part of a group of xorg packages (proto, fonts, etc)
#    there is no easy way to extract it from the xml. We use the ENTITY at
#    the top of each file x7*.xml
#  - If a pacakge is versioned but the version is not mentioned in the book
#    (currently only udev), we retrieve the version by other means
#-------------------------------------------------------------------------
# Arguments:
# $1 contains the name of the validated xml book
# $2 contains the name of the ouput xsl file
# $3 contains the name of the book sources directory
