[gentoo-dev] Add LCD_DEVICES to USE_EXPAND

[Robert Buchholz]

Hi *,

both app-misc/lcdproc and app-misc/lcd4linux can use numerous kinds of
displays. The device selections are right now handled via environment
variables and/or single use flags.

I would like to unify possible devices via the USE_EXPAND'ed
LCD_DEVICES. Right now, this would contain about 50 devices [1].

Out of these, some common devices should be installed by default (these
are considered default by lcdproc upstream, too):
    LCD_DEVICES="bayrad CFontz CFontz633 curses CwLnx glk lb216 lcdm001
                 MtxOrb pyramid text"

This will of course introduce changes in the configurations for lcdproc
and lcd4linux users, but I think that it needs to be done and the
changes are mostly renaming USE flags and environment variables.

If no one objects, I'd like to implement these changes. But there are
some questions still open:
* Who will add the entries to base/make.defaults? Can I do this?
* Should the defaults and the USE_EXPAND entry be in base/ even though
  both programs do not are not keyworded for all arches?

Regards,

Robert
