[GRASS-user] test if raster/vector exists (in Perl)

I have a Perl program that loops through the r.lake module, and captures
output.  In the program, there are a few instances where I would like to
test if a given raster already exists.  In perl, its something like this to
test if a file exists ... if (-e "filename") { do stuff }.

is there a way to use this feature against a raster?  Otherwise, I was going
to do something like r.info and pipe the output to a file.  then search that
the file for some keyword indicating it exists or doesnt exist.

any other ideas or approaches?
