This subset contains most of the Athena applications, other than those specifically mentioned above. It requires the Athena Basic Services, and the X subset is recommended. Some applications will not run without those subsets loaded. Some of the more notable applications include: olh, delete, mh, rcs, tcsh, eos, imake, notes, kerberized remote access, discuss, dash, perl, and much more. Note that while olh may be copied to the local disk, the documentation database may not be copied local. Not allowing this dynamic database to be copied local assures that the information will not grow stale.
