Log Message:
- Allow '^' to appear unquoted in shell programs, although it ``is an
  obsolete synonym for the pipe operator "|", so you must protect it with
  quotes''. (Kernighan/Pike, The UNIX Programming Environment, 1984.)
- $@ is another well-known shell variable.
- All substitution arguments to ${SED} and ${PAX} should be quoted whether
  they contain special characters or not.
