+ A slightly more secure method is to store the authorization information in
+ environment variables (for UNIX, djgpp, and Win32, at any rate -- not sure
+ about VMS.) Environment variables are not visible with the `ps' command on
+ most systems. Perhaps LYNXAUTH is a good name?

Environment variables *ARE* available to PS, on _most_ unix systems.   *sigh*
On a BSD-based system, see the '-c' (show _real_ command-line) and '-e' (show
environment) flags.  On SYSV, it -always- does the equivalent of '-c'.  There
is an equivalent to the '-e' flag, too, but I don't remember what it is.

The *only* _approximatly_reliable_ secure way to do this is have the info _in_
_a_file_, and to NOT trust the file, unless it is mode 700, and _owned_ by the
current user.
