                    Tecplot upgrade to release 7.5

Tecplot 7.5 will become the Athena default in about 4 weeks. To 
run it now, do:

	add tecplot
	tecplot -ver 7.5 &

at the Athena prompt. To run demos and get an overview of new
features, type "rundemo -ver 7.5" after adding the tecplot locker.

A new feature of this release is that the complete User's Manual and
Reference Manual are available online, in Adobe Acrobat format,
in files /mit/tecplot_v7.5/distrib/doc/75rm.pdf and
/mit/tecplot_v7.5/distrib/doc/75um.pdf respectively.

If data files created by release 7 or earlier are opened in version
7.5, they will be automatically converted to a new, incompatible
format. if these converted files are resaved from within Tecplot 7.5,
they will not be readable by Tecplot 7.

After the change, you will still be able to run Tecplot 7 by typing:

	add tecplot
	tecplot -ver 7 &

at the Athena prompt.
