   get_dom() will retrieve domain configuration information from a GDBM file
   in /home/httpd/lonUsers/$dom on the primary library server in a domain.
   The single argument passed is the string: $cmd:$udom:$namespace:$what
   where $cmd is the command historically passed to lond - i.e., getdom
   or egetdom, $udom is the domain, $namespace is the name of the GDBM file
   (encconfig or configuration), and $what is a string containing names of
   items to retrieve from the db file (each item name is escaped and separated
   from the next item name with an ampersand). The return value is either:
   error: followed by an error message, or a string containing the value (escaped)
   for each item, again separated from the next item with an ampersand.
