+# Usage: get-scala-commit-sha [dir]
+# Figures out current commit sha of a git clone.
+# If no dir is given, current working dir is used.
+#
+# Example build version string:
+#   6f1c486d0ba
+#
+
+[[ $# -eq 0 ]] || cd "$1"
+
+# printf %016s is not portable for 0-padding, has to be a digit.
+# so we're stuck disassembling it.
