[RegCNET] MPI-GCM data as RegCM input

[BI XUNQIANG]

Dear RegCMer:

It would be better if Moetasim's email was not Cc to RegCNET. As I
told the small group, the EH5OM.tar.gz is only half done for the
following reasons:

1) We plan to update the code related to the Common Land Model
under the Main directory (hopefully we could make it done in 40 days).

2) The TerrainS directory is not well ready at this moment (for the
coupling of CLM).

3) I am in Beijing right now, it's impossible for me to prepare the
window-size EH5OM datasets for other region (in 40 days).

I really hope that Moetasim wouldn't make the same mistake in future,
you know, it's ICTP RegCM3 group's responsibility that we could only
give all the RegCMers the code as perfect as possible. Please not
force us to distribute the half-done code.

By the way, I have renamed the EH5OM.tar.gz file, so the file is
not available now.

Best regards,
Xunqiang
