.SH DESCRIPTION
The gopher client is used to talk to gopher servers.  Once you have started
the gopher client, help on using it is available by pressing the 
.B "?"
key.
.PP
The Internet Gopher is a distributed document delivery service.  It
allows a neophyte user to access various types of data residing on
multiple hosts in a seamless fashion.  This is accomplished by
presenting the user a hierarchical arrangement of documents and by
using a client-server communications model.  The Internet Gopher
Server accepts simple queries, and responds by sending the client a
document.
.PP
The [hostname] of a gopher server may be specified at startup; if
omitted, the default server for your site is used.  You may also
specify a URL (Uniform Resource Locator) for this argument.
.PP 
The  [Port_number] of the server host may be specified at startup; if
omitted you will use the default port specified at your site.  The
more or less standard and accepted Gopher port number on the
Internet is 70.
.PP
.SH OPTIONS
.TP
-b
starts the client on the bookmark page.
.PP
The next few options are for more advanced users who want to start at
a location other than the default, or to set up special aliases or
shell-scripts to point the gopher client to seperate places.
.TP
.BI -p " path"
specify a specific selector string to send to the gopher server on startup.
.TP
.BI -T " type"
let the client know what type of object the
.I -p
option is pointing at.
.TP
.BI -i " search term"
tell the client what to search for in the object defined by the
.IR "-p " and " -T 7"
options.
.TP
.BI -t " title"
set the title of the initial screen for the gopher client.

.PP
The last few options aren't really of interest to regular users, but are
provided for system administrators who waht to provide a secure client, or
who need to debug a client.

.TP
.BR -s " or " -S
"secure mode" which means that you can't save or print the files that you
browse.  -s is for users without an account, while -S assumes 
the user has an account on this machine.  One security feature is
forced on, regardless of the state of these options, if the name of
the user's shell ends in rsh; the 'O' (options) command is disabled so
the user cannot select a shell as an application.
.TP
.B -r
tells the client that its user is remote.
.TP
.B -D 
turns on the copius debugging output
