     37 # Configuration subroutine to validate and canonicalize a configuration type.
     38 # Supply the specified configuration type as an argument.
     39 # If it is invalid, we print an error message on stderr and exit with code 1.
     40 # Otherwise, we print the canonical config type on stdout and succeed.

     56 # or in some cases, the newer four-part form:
