+Usage: ${HILITE}crossdev${NORMAL} ${GOOD}[options]${NORMAL} ${BRACKET}--target TARGET${NORMAL}
+
+Options:
+    ${GOOD}--b, --binutils${NORMAL} ver   Specify version of binutils to use
+    ${GOOD}--g, --gcc${NORMAL} ver        Specify version of gcc to use
+    ${GOOD}--k, --kernel${NORMAL} ver     Specify version of kernel headers to use
+    ${GOOD}--l, --libc${NORMAL} ver       Specify version of libc to use
+    ${GOOD}-S, --stable${NORMAL}          Use latest stable versions as default
+    ${GOOD}-C, --clean${NORMAL} target    Uninstall specified target
+    ${GOOD}-P, --portage${NORMAL} opts    Options to pass to emerge (see emerge(1))
+Stage Options:
+    ${GOOD}-s0, --stage0${NORMAL}         Build just binutils
+    ${GOOD}-s1, --stage1${NORMAL}         Also build a C compiler (no libc/C++)
