SEE ALSO

94       The documentation for Macaulay2 is available locally starting in ${pre‐
95       fix}/share/doc/Macaulay2/Macaulay2Doc/html/index.html,  where ${prefix}
96       is  replaced  by  the  directory  prefix  used  when  the  package  was
97       installed.   The  directory  is available as the value of the Macaulay2
98       variable prefixDirectory, but the best way to get to the  documentation
99       is to run the command viewHelp in Macaulay2.
