SlackBuildsOrg/system/google-droid-fonts

The Droid typeface family was designed in the fall of 2006 by Ascender's 
Steve Matteson, as a commission from Google to create a set of system 
fonts for its Android platform.  The goal was to provide optimal quality 
and comfort on a mobile handset when rendered in application menus, web 
browsers, and for other screen text.

This package installs /etc/fonts/conf.avail/35-droid.conf which sets the
"sans" and "serif" and "monospace" aliases to Droid fonts.  If you want 
to use Droid as your system fonts, symlink it into /etc/fonts/conf.d/
