[yt-users] Not able to read 2D BoxLib files

[Mani Chandra]

Hi Andrew,

This is a code which I'm writing now using the BoxLib framework, so it is
not exactly any of Nyx, Castro, Maestro or Orion. But I thought that since
they all use BoxLib, I could simply use any of those frontends (although
those frontends require a lot of parameters specific to those codes, which
I just commented out).

So I guess I'll have to write a frontend then.

Thanks,
Mani
