+#!/bin/bash
+#
+# Find a native sysroot to use - either from an in-tree OE build or
+# from a toolchain installation. It then ensures the variable
+# $OECORE_NATIVE_SYSROOT is set to the sysroot's base directory, and sets
+# $PSEUDO to the path of the pseudo binary.
+#
+# This script is intended to be run within other scripts by source'ing
+# it, e.g:
+#
+# SYSROOT_SETUP_SCRIPT=`which oe-find-native-sysroot`
+# . $SYSROOT_SETUP_SCRIPT <recipe>
+#
+# This script will terminate execution of your calling program unless
+# you set a variable $SKIP_STRICT_SYSROOT_CHECK to a non-empty string
+# beforehand.
