+Usage: gcc-config [Option] [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.
+	
+  -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.
+
+  -E, --print-environ
+                         Print environment that can be used to setup things
+                         for current gcc profile, or specified one ...
+	
+  -B, --get-bin-path
+                         Print path where binaries of given/current profile
+                         are located.
+	
+  -L, --get-lib-path
+                         Print path where libraries of given/current profile
+                         are located.
+
+  -X, --get-stdcxx-incdir
+                         Print path to g++ include files of given/current
+                         profile.
+	
+The profile name is in the form of:
+
+  <CHOST>-<gcc version>
+
+For example:
+
+  i686-pc-linux-gnu-3.2.1
