There's no tutorial yet. However:

# The following is a demonstration of a layer which would be generated
# according to the 'Google projection'. Note that EPSG:900913 is a play
# on a lowercase 'google' in "leet-speak" -- it is not an official EPSG

#[google-tiles]
#type=WMSLayer
#url=http://localhost/cgi-bin/mapserv?map=/mapdata/world.map
#layers=world
#bbox=-20037508.3427892,-20037508.3427892,20037508.3427892,20037508.3427892
#maxResolution=156543.0339
#srs=EPSG:900913

 tms_type
    Setting this to "google" will cause tiles to switch vertical order
    (that is, following the Google style x/y pattern).

so, you want the above, plus 

tms_type=google

And you'll want to get the SRS for EPSG:900913 from the
spatialreference.org link.
