+# On systems which use the bash-completion module for
+# completion discovery with bash, this can be installed at:

+#   pkg-config --variable=completionsdir bash-completion
+#
+# If BuildStream is not installed system wide, you can
+# simply source this script to enable completions or append
+# this script to your ~/.bash_completions.
