Hi Bernhard,
this is a good idea: We can hide modules in $GISBASE/etc (there
are already several hidden modules) and call them by a
general output module.
Any volunteers out there 
?
Well, That is my next grass project A full interactive map
composer system (with a tcl/tk interface, so it can also be run
on the windows version of grass). The actual state is paper and
pencil thinking, list of desired functionnalities, and the desire
for a modular/customisable/reusable system.
In brief :
- interactive placement of the differents modules (map, legend,
frames, lines, coordinates cross, texts, images, ...) on the map,
with previsualisation (à la nviz) : modules can overlap like
windows on a screen.
- layer stack for printing on the same map more than one raster,
any number of vector files or site files in a selected order
- icon editor for sites representation
- icon size/color/orientation/type may be linked to site attributes
- line representation (width, dashed/dotted/symbols, inside/ouside
color, non symetrical aspect) parametrable by line attributes
- area filling either with grass color, or with pattern/color
defined in a library (like line representation or icon)
- any defined map may be resused in a frame on an other map (copy/
cut/paste) => "map library" for mapping different places with
the same overall aspect (region not linked to representation).
The layout of a map can be saved, recalled and quickly modified
for an other output. (in $LOCATION/map ?)
- automaticaly created, but customisable legend
- scale bar/north arrow as icon
- output : originaly postscript only, including the icons format,
with the use of gs to make images, but maybe also a xfig output
(in many files if there is rasters/images on the output) and the
use of xfig as a graphic editor for symbols ?
- Paper coordinate system for the placement, map coordinate system
inside each map and for the text inside it.
- Paper size... well, any + a list of well known formats (metric+US)
- The module for the map itself should be usable as a replacement
for d.rast/vect/site... (some kind of basic Mapinfo or Arcview ?)
What else ? Anybody else interested ?
