Returns a remote document. Remote documents in Hyperwave
notation are documents retrieved from an external source.
Common remote documents are for example external web pages or
queries in a database. In order to be able to access external
sources throught remote documents Hyperwave introduces the
HGI (Hyperwave Gateway Interface) which is similar to the
CGI. Currently, only ftp, http-servers and some databases can
be accessed by the HGI. Calling
hw_getremote() returns the document from the external
source. If you want to use this function you should be very
familiar with HGIs. You should also consider to use PHP
instead of Hyperwave to access external sources. Adding
database support by a Hyperwave gateway should be more
difficult than doing it in PHP.
