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