[Debian-med-packaging] Bug#813972: libncl-dev and libncarg-dev: error when trying to install together

[Andreas Tille]

Hi Mark,

the Debian Med team has packaged your NCL library for the Debian
distribution.  We received a bug report that there is a naming conflict
with

    http://www.ncl.ucar.edu/

My suggestion to solve this conflict would be to rename libncl to
libnexus.  In my opinion it would make sense to rename it in general
since it is a more speaking name than ncl.

What do you think?

Kind regards and thanks for providing this code as free software

     Andreas.
