[petsc-users] Installing Petsc

[Dharmendar Reddy]

Hello Matthew,
                       I Do i need to download the external packages again?
I mean, if i give the download options again and add debuggin=no, will the
packages be downloaded again or will they be used from the existing
downloads in the folder external packages ?
