Description
------------------------------------------------------------------------
A simple set of macros to provide markup devices (currently only
grohtml) with tags that define the meaning of the formatted text and
also basic formatting instructions. It generalizes the tag concept used
within grohtml and in the future it is hoped that more markup based
devices can capitalize on this work. It also clearly defines those tags
which are honoured by grohtml. Note that not all tags are included
here. Some of the grohtml specific tags (header specific and jobname,
etc.) are called directly from within www.tmac. The tags defined here
are reasonably generic and could be applied to other devices.
