/** <module> Brand the SWISH installation

This config file changes the page  title   and  SWISH  logo. Branding is
achieved by proving Prolog hooks for the page generation. Icon resources
may be placed in  `config-enabled/web/icons`.   Icons  placed there that
precedence over icons in the `web/icons` directory of SWISH itself. Note
however that many small icons are compiled into the minified CSS file.

The branding in this file is for the VRE4EIC project that supported part
of the development of SWISH.
