 `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
 ```
