source: trunk/gsdl/src/recpt/documentaction.cpp@ 10873

Last change on this file since 10873 was 10873, checked in by jrm21, 19 years ago

documentaction modified for new HTML4/CSS stuff (eg stop looking for
icon width macros). Other files modified to tidy up output (put tag
attribute values in quotes, use & instead of &, etc). Not quite
finished yet but it works.
