[FASTCGI] difference between apache's mod_fcgi, mod_cgid, and mod_fcgid?

[Tom Bowden]

Is the difference between these modules just a matter of version?  I  
am using Apache 2.2+ server -- and it uses mod_fcgid... from what i  
can tell the big difference is that the configuration keywords are  
difference ( FcgidAuthenticator, FcgidAuthorizer, FcgidAccessChecker,  
FcgidWrapper, etc.).
