#  Modified by Jeffrey H. Kingston, 22 June 1993, to (a) add an option to     #
#  turn off running titles; (b) fix a bug which was allowing an odd number    #
#  of introductory pages to be generated; (c) bring English-language          #
#  specific parts to the surface so that they can be changed easily; (d)      #
#  fix a bug with @BeginFigures and @BeginTables.                             #
