I note that on search.cpan.org, on the page for DBD::Oracle, the files "README.hpux" and "README.vms" appear in the section "Documentation," but that files like "README.aix" and "README.win32" appear in the section "Other files."
I'm very curious to find out what is different about the README files for these two platforms that causes them to be set apart in this special section.
