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  in‐
88       stalled.   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.
