Hi Nico,

Right, Unidata support for libCF development was halted about 2 years
ago, after the primary developer left Unidata.

> Also, the website <http://www.unidata.ucar.edu/software/libcf/>

The most recent version, from April 2012, is still available from

   ftp://ftp.unidata.ucar.edu/pub/libcf/libcf-1.0-beta10.tar.gz

The main development focus at the end had been implementing an API
for GRIDSPEC, in collaboration with a DOE-funded project, but that
library was never completed.  There are currently better approaches
for conservative regridding in the ESMF regridding software:

   http://www.earthsystemmodeling.org/esmf_releases/last/regridding_status.html

and its Python interface in ESMPy.

The most recent active implementation of a library for the CF
Conventions is cf-python, at

   http://cfpython.bitbucket.org/
