+# Requirements: 
+# * Broadcom Low Power wireless card
+# * Kernel newer than 2.6.32
+# * Root permissions
+#
+# This script installs firmware for supported Broadcom b43 low power devices.
+# Most of it was ripped out of the firmware-b43-lpphy-installer Debian
+# package, but it is meant for use on other distros.
+# 
+# A quick-n-dirty way to tell if you need this firmware is to run:
+#     lspci | grep LP-PHY
+# But a more sophisticated test is included in the script. If you want to 
+# install the firmware even if the test fails, just delete the relevant 
+# lines.
+
+# check chip
