2.1 What version of Emacs can be used?

You can run emacs-w3m in various versions of Emacsen listed below:

`Emacs 21.x'

No additional packages are required.

`Emacs 22.x'

No additional packages are required. If you're using a prerelease version of Emacs 22 (such as versions 21.3.50 or 22.0), make sure it is newer than March 2004.

`XEmacs 21.x'

The APEL package and the `gifsicle' program are required (see section 2.3 Things required to run emacs-w3m). We recommend using the latest XEmacs 21.4 which seems stable.

`Emacs 20.x'

No additional package is required. Furthermore, you can see monochrome bitmap images inline by using the BITMAP-MULE package (see section 2.3 Things required to run emacs-w3m).

`Emacs 19.34 (including Mule 2.3)'

The APEL package, the `new custom' package and the `regexp-opt.el' module are required. If you are using Mule 2.3 based on Emacs 19.34, you can see monochrome bitmap images inline by using the BITMAP-MULE package (see section 2.3 Things required to run emacs-w3m).
