# Extension to LaTeX2HTML to translate LaTeX commands
# for justified paragraphs and environments.
# The HTML markup is not part of HTML 2.0 but is part
# of the recommendations for HTML 3.2.
# Currently it is recognised by popular browsers;
# e.g. Netscape Navigator.
#


# These are also implemented in the file:  versions/html3.0.pl
# which is automatically loaded for sufficiently large 
# values of  $HTML_VERSION .
