.SH DESCRIPTION
|
|
.I Mothra
|
|
uses
|
|
.IR webfs (4)
|
|
to retrieve and display files from the World-Wide Web,
|
|
by name or through hypertext links.
|
|
Web names, called URLs, have a peculiar syntax:
|
|
.IP
|
|
.EX
|
|
http://netlib.att.com/netlib/1127/www/1127.html
|
|
http://akebono.stanford.edu:80/yahoo/
|
|
http://www.teleport.com/~crowell/
|
|
ftp://ftp.gmd.de/music/scores/harrington/Harrington.readme
|
|
.EE
|
|
.PP
|
|
The part up to the first colon gives the protocol for
|
|
retrieving the file.
|
|
.BR http: ,
|
|
Hyper-Text Transfer
|
|
Protocol, is the usual way of accessing web files.
|
|
.B ftp:
|
|
and
|
|
.B gopher:
|
|
are standard Internet services.
|
|
.PD
|
|
.PP
|
|
.B //
|
|
begins the Internet address of the server where the file resides.
|
|
The address may contain a colon and a TCP port
|
|
number, which overrides the
|
|
default port number for the service. Next comes a
|
|
file name. Finally, the file name may be followed by
|
|
.B #
|
|
and a string giving a label within the file where the
|
|
display should begin.
|
|
.PP
|
|
.I Mothra
|
|
starts with the
|
|
.I url
|
|
given on the command line, defaulting to
|
|
the environment variable
|
|
.BR $url .
|
|
.PP
|
|
There are a number of options:
|
|
.TP
|
|
.B -d
|
|
Debug mode.
|
|
.TP
|
|
.B -m
|
|
Specify the
|
|
.IR webfs (4)
|
|
mountpoint with
|
|
.BR -m
|
|
.I mtpt.
|
|
The default is
|
|
.B /mnt/web.
|
|
.TP
|
|
.B -v
|
|
Verbose mode. Causes HTML errors to appear in
|
|
.B $home/lib/mothra/mothra.err
|
|
.PP
|
|
The display contains the last message from
|
|
.I mothra,
|
|
a box where typed commands appear,
|
|
a scrollable list of previously visited files,
|
|
the title and URL of the current file,
|
|
and the scrollable text of the current file.
|
|
.PP
|
|
Button 1 selects and displays a file, either from the list
|
|
of previously visited pages or from a link (indicated
|
|
by underlined text or a boxed image) in the
|
|
current file. Button 2 shows the URL of a file,
|
|
but does not retrieve or display it.

|

When
|
|
.I mothra
|
|
retrieves a file that is not an
|
|
HTML document (for example a GIF or JPEG
|
|
image), it will start up an appropriate viewer, for example
|
|
.B page
|
|
(see
|
|
.IR page (1))
|
|
for most image files.

|
.SH BUGS
|
|
Files are saved in the form received,
|
|
not in the form suggested by the name in an
|
|
.B s
|
|
command. A directory index saved from moth mode may be written in
|
|
the local directory as a file named
|
|
.B index.
|
|
Sanitizing remote file names for the local file system is imperfect.
|
|
.PP
|
|
.I Mothra
|
|
is distributed in a preliminary state; it has more than its share of bugs. Note that
|
|
.I mothra,
|
|
like the other Guardian Monsters, has no particular concern for humanity.
