An interesting cross-platform driving game ; as of the date of
this posting it's still in it's beta stages and the windows
version is more maintained/featured than the other ports now
available.
Due to it's work-in-progress nature, this title does =not= come
with an installer -- it is currently distributed as a .zip archive,
so basically first create a new bottle and then unzip the archive
and copy the contents into the bottle ; use the cxsetup utility
and control-panel to create a (desktop) link to racer.exe and it
should work.
