Dear Gentooers,

Is there a place in gentoo documentation where there is a complete list of current USE flags and short descriptions what they mean? I am just a user, and I think the fantastic idea of a custumized linux system will only work if users can fully understand which USE flags are available what they mean, etc. 

I am just getting used to portage (even though I used binary distros for years) and sometimes I do not know what the advantages and consequences of a particular USE flag to be set... 

Appreciate for any help or pointers to do some RTFM.

Thanks:  Viktor
