The supported version of LaTeX on Athena is currently 2.09, but
there are usually seperate installations of newer versions available.
Currently, (LaTeX ) is available in the newtex
locker. You can access it by:
add newtex latex2e filename.tex
at the athena% prompt. In general, you can access the new
version of LaTeX by default via the commands:
add -f -e newtex latex filename.tex
In both cases, the ``add'' line may be placed in the
.environment file. These versions of LaTeX are sometimes
less stable than the default Athena version, and you may find that it
takes longer for OLC to respond to questions about these versions, but
they are generally useable.
