- Bug 6629.
  - Re-enable access to functionality in Math::Complex in Safe Space by
    copying Math::Complex 1.55 to LONCAPA::LCMathComplex and eliminating use
    of Config.pm
    - Whenever ./UPDATE is run to install or update LON-CAPA, the code which
      sets $nvsize in the standard Math::Complex script will be run in
      lcmathcomplex.piml and the value of $nvsize will be set to the
      appropriate value: 4, 8, 10, 12 or 16 in LONCAPA/LCMathComplex.pm.
