GRASS -> IDRISI scripts?

[spf at hoqaa.att.com]

Hi folks,

Before I go reinvent the wheel, does anyone have shell scripts which
convert GRASS raster and vector files into their IDRISI equivalent?

I need to use IDRISI for a highly mobile, portable application, but most
(if not all) of the data I will need is available in GRASS formats. 
I know (or think I know) that I can write scripts to do the conversion,
but I'd rather use some else's.

Thanks!
