[FWTools] Question About Shapefile Reprojection With FWTools/OGR2OGR

I'm using FWTools for the first time, and I'm trying to figure out the
command I would use to get OGR2OGR to perform a coordinate
transformation on an ESRI Shapefile. I can't seem to get the syntax
for the command correct, and I was hoping to get some help here.

I'm trying to reproject a shapefile named "roads.shp" from WGS84 to
California State Plane Zone 3. The resulting file should be named
new_road.shp. I know my EPSG codes are 4326 and 2227.

Here is the command that I think is the closest to what I need, after
some trial and error:

ogr2ogr -s_srs EPSG::4326 -t_srs EPSG::2227 -f "ESRI Shapefile"
C:/Temp/my_data/roads.shp C:/Temp/my_data/new_roads.shp

ogr2ogr reports that EPSG::2227 is not found in the support files. I
thought this was a fairly common map projection. Is there a problem
with my command syntax? Do I need to add support for this EPSG code to
FWTools? Can you point me towards the documentation I would use to do
