Ryan,
The commandline program "gdaltindex" in the FWTools distribution
will do this. It is intended for creating a shapefile as a "tile index"
for a bunch of GeoTIFF files or other files. For each supported
raster file on the commandline, it wll add a record to a shapefile
with the geometry being a polygon footprint (really the bounding
box I think) and the attribute being the filename.
You would use it something like:
gdaltindex doq_index.shp doq/*.tif
The FWTools suite can be found at the following page, and includes
binaries for Linux and Windows.

Best regards,
