+Usage: binutils-config [options] [binutils profile]
+Change the current binutils profile, or give info about profiles.
+
+Options:
+ -c, --get-current-profile Print current profile
+ -l, --list-profiles Print a list of available profiles
+ -u, --uninstall Remove all signs of specified target
+
+Profile names are of the form: <CHOST>-<binutils version>
+For example: x86_64-pc-linux-gnu-2.15.92.0.2
