Do any tools exist to import GIRAS data? (fwd)

Forwarded message:

Is anyone aware of any tools to import GIRAS data into
GRASS. All of the 1:250K land use and land cover data
available from the USGS ftp site are in GIRAS format.
Apparently, the LULC data is also available in Composite
Theme Grid (CTG) format as well. CTG is similar to a raster
layer and GIRAS is similar to a vector polygon layer.
I need an answer pronto and would appreciate an update.
I checked the archives and these tools seem to be under
construction. Thanks for any help in advance!!

The module m.lulc.USGS reads the CTG format for these
files.
