Running perldoc Koha gives documentation for Koha.pm, which currently contains the koha version number. ... but the other reason one might want to run 'perldoc Koha' is as an entry point for documentation for the entire koha project. I think we should expand SEE ALSO C4::Context kohaversion.pl To point to the major modules in Koha -- Koha::Objects, C4::Circulation, the development section of the Koha wiki, Koha documentation, etc.
Closing this one due to age...
