+# modified to support mutiple architectures for toolchain
+# testing. DMUCS sends the CPU load to a server, which we can query
+# using the 'gethost' command to get the next available slave for a
+# remote test based on which one is the least busy. The code for this
+# enhanced DMUCS is at: http://git.linaro.org/git/toolchain/dmucs.git
