[SIESTA-L] use of packages

[Neranjan Perera]

HI siesta users,

    I do have a question about the options when configuring siesta.

what kind of use do I get when I compiled the program with the "Optional
Packages" such as;

--with-netcdf
--with-blacs
--with-scalapack

I highly appriciate some explanation on the above. Thank you very much for
your time.

Thanks

Sincerely,
Neranjan
