+  -f, --force                Make sure all config files are regenerated.
+  -P, --use-portage-chost    Only set to given profile if its CHOST is the 
+                             same as that set for portage in /etc/make.conf
+                             (or one of other portage config files...).
+  -c, --get-current-profile  Print current used gcc profile.
