SEE ALSO

85       The documentation for Macaulay2 is available locally starting in ${pre‐
86       fix}/share/doc/Macaulay2/Macaulay2Doc/html/index.html,  where ${prefix}
87       is  replaced  by  the  directory  prefix  used  when  the  package  was
88       installed.   The  directory  is available as the value of the Macaulay2
89       variable prefixDirectory, but the best way to get to the  documentation
90       is to run the command viewHelp in Macaulay2.
