* Profiles sets all the default values for the client's [http://dev.gentoo.org/~zmedico/portage/doc/man/make.conf.5.html <code>make.conf</code>], such as USE flags, BINHOSTS, GENTOO_MIRRORS, CFLAGS, CHOST etc.
** '''Warning''': many such variables are not incremental and therefore need duplication of Gentoo base profile variables (requiring that someone tracks changes in those variables) --[[User:Tiziano|Tiziano]] ([[User talk:Tiziano|talk]]) 14:29, 3 January 2014 (CET)
