The 'domains' command allows you to query the current server about the
 archie 'pseudo-domains' that it supports.

 The archie system has the concept of "pseudo-domains". This is primarily
 for the convenience of being able to specify things like 

 "usa" instead of ".gov" and ".com" and ".edu" and ".us" etc.

 Pseudo-domains are composed of normal Domain Name System (DNS) domains
 and other pseudo-domains and each archie server administrator may define
 them aribtrarily. Ultimately all pseudo-domains should resolve into a
 list of actual DNS domains. For example, the system administrator may
 define the pseduo-domain "eastcoastu" to be "massu:nyu:princeton.edu"
 (universities in Mass., New York and Princeton University). They could
 then define "massu" to be "harvard.edu:bu.edu" (Harvard and Boston
 Universities) and "nyu" to be "nyu.edu:columbia.edu" (NY University and
 Columbia).

 Thus "eastcoastu" would ultimately be

 "harvard.edu:bu.edu:nyu.edu:columbia.edu:princeton.edu"
