\fIw3m\fP is a text based browser which can display local or remote
web pages as well as other documents.
It is able to process HTML
tables and frames but it ignores JavaScript and Cascading Style
Sheets.
\fIw3m\fP can also serve as a pager for text files named as
arguments or passed on standard input, and as a general purpose
directory browser.

\fIw3m\fP organizes its content in buffers or tabs, allowing easy
navigation between them.
With the w3m-img extension installed, \fIw3m\fP can
display inline graphics in web pages.
And whenever \fIw3m\fP's HTML
rendering capabilities do not meet your needs, the target URL can be
handed over to a graphical browser with a single command.

For help with runtime options, press \(lqH\(rq while running \fIw3m\fP.

.SH ARGUMENTS

When given one or more command line arguments, \fIw3m\fP will handle
targets according to content type.
For web, \fIw3m\fP gets this
information from HTTP headers; for relative or absolute file system
paths, it relies on filenames.

With no argument, \fIw3m\fP expects data from standard input and
assumes \(lqtext/plain\(rq unless another MIME type is given by the user.

If provided with no target and no fallback target (see for instance
option \fB\-v\fP below), \fIw3m\fP will exit with usage information.
