 # This package implements the support for external toolchains, i.e
-# toolchains that have not been produced by Buildroot itself and that
-# Buildroot can download from the Web or that are already available on
-# the system on which Buildroot runs. So far, we have tested this
+# toolchains that are available pre-built, ready to use. Such toolchain
+# may either be readily available on the Web (Linaro, Sourcery
+# CodeBench, from processor vendors) or may be built with tools like
+# Crosstool-NG or Buildroot itself. So far, we have tested this
 # with:
 #
 #  * Toolchains generated by Crosstool-NG
