Using Macaulay 2 sessions inside <TeXmacs>
</expand>
<name|Macaulay 2> is a software system devoted to supporting research in
algebraic geometry and commutative algebra. The software is available now
in source code for porting, and in compiled form for <name|Linux>,
<name|Sun OS>, <name|Solaris>, <name|Windows>, and a few other unix
machines. You can get it from
<\verbatim>
\ \ \ \ http://www.math.uiuc.edu/Macaulay2
</verbatim>
Here follows a sample session, which was started using
<apply|menu|Text|Session|Macaulay 2>:
