+Usage: gcc-config [options] [CC Profile]
+Change the current cc/gcc profile, or give info about profiles.
+
+Options:
+  -O, --use-old              Use the old profile if one was selected.
+  -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.
+  -l, --list-profiles        Print a list of available profiles.
+  -S, --split-profile        Split profiles into their components
+  -E, --print-environ        Print environment that can be used to setup the
+                             current gcc profile, or a specified one.
+  -B, --get-bin-path         Print path where binaries of the given/current
+                             profile are located.
+  -L, --get-lib-path         Print path where libraries of the given/current
+                             profile are located.
+  -X, --get-stdcxx-incdir    Print path where g++ include files of the
+                             given/current profile are located.
+
+Profile names are of the form:  <CHOST>-<gcc version>
+For example:                    i686-pc-linux-gnu-3.2.1
