[GRASSLIST:864] GMT / GRASS use / shp2gmt

[Trevor Wiens]

Grudgingly I'm using GMT after working through Dylan's example and am
getting it to be somewhat functional.

I will be needing to script the building of a large number of maps
which I may store either in PostGIS or GRASS. 

I've noticed in the use of shp2gmt that there is no way of adding in a
z attribute for use with the thematic colour assignment feature in GMT.
If necessary I can extract bits based on different attributes and add
them in separately, but it would be nice to be able to simply define a
colour them once and be done with it. Any suggestions on how I can turn
an attribute column in GRASS into a z-element that will be converted
with shp2gmt would be appreciated.
