[petsc-dev] remnants of pkg-config in BuildSystem?

[Barry Smith]

   In BuildSystem I find 

   if hasattr(self, 'usePkgConfig') and 'with-'+self.package+'-pkg-config' in self.framework.argDB:
      self.framework.argDB['with-'+self.package] = 1
      self.usePkgConfig()

and 

    if hasattr(self, 'usePkgConfig'):
      help.addArgument(self.PACKAGE, '-with-'+self.package+'-pkg-config=<dir>', nargs.ArgDir(None, None, 'Indicate the root directory of the '+self.name+' installation'))

not signs of any implemented usePkgConfig()

   Am I missing something or are these just plans that never came to fruition?

   Thanks
