+Running `./sbt.sh` emits `./sbt.sh: 2: ./sbt.sh: source: not found`
+====
+
+This is due to the usage of `source` within the scripts.
+
+There are two potential fixes:
+
+* Change `#!/bin/sh` to `#!/bin/bash`
+* Change `source` to `.`
+
+I'm doing the ladder one...
+
+* `find . -name "*.sh*|xargs -n1 sed -i "s/source /. /"`
