/sys$common/syshlp/helplib.hlb PRODUCT, CONFIGURE, Example  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  $ PRODUCT CONFIGURE EDITOR -
  _$ /CONFIGURATION=(INPUT=EDITOR_REV1.PCF,OUTPUT=EDITOR_REV2.PCF)

      The command in this example reads an existing PCF file named
      EDITOR_REV1.PCF for a product named EDITOR and then saves your
      changes in EDITOR_REV2.PCF.
