DESCRIPTION
r3.support allows the user to create and/or edit raster3d map support information. Editing of raster3d map units, history, description and title is supported.

NOTES
Freeform metadata information is stored in a "hist" file which may be appended to by using the history option. Currently this is limited to text with a maximum line length of 78 characters. Any input larger than this will be wrapped to the next line. All other metadata strings available as standard options are limited to 79 characters.
