 `GBB_PATH` is a place that mkuimage will look for commands. Each colon-separated
 `GBB_PATH` element is concatenated with patterns from the command-line and
 checked for existence. For example:
 
 ```shell
-GBB_PATH=$HOME/u-root:$HOME/u-bmc mkuimage \
-    cmds/core/init \
-    cmds/core/gosh \
-    cmd/socreset
-
-# matches:
-#   $HOME/u-root/cmds/core/init
-#   $HOME/u-root/cmds/core/gosh
-#   $HOME/u-bmc/cmd/socreset
+GBB_PATH=$(pwd)/u-root:$(pwd)/cpu mkuimage \
+    cmds/core/{init,gosh} \
+    cmds/cpud
+
+# Matches
+#   ./u-root/cmds/core/{init,gosh}
+#   ./cpu/cmds/cpud
 ```
