maybe some hints about possibilities to distinguish between different
Alberta versions. One possibility is

alberta.h, version 1.2:
#define ALBERTA_VERSION  "ALBERTA: Version 1.2 "

alberta.h, version 2:
#define ALBERTA_VERSION  "ALBERTA: Version 2.0"

alberta.h, version 3 (but also almost any of the pre-releases)
#define ALBERTA_MAGIC   "ALBERTA: Version "
#define ALBERTA_VERSION ALBERTA_MAGIC"2.3 "

Note that this has nothing to do with the release number of Alberta,
but tags different formats of the data files the Alberta-FEM-toolbox
dumps to disk.

Further:
libalberta_util has been renamed to libalberta_utilities for V3

In V3 there are some new header files in INCLUDE/alberta/
el_vec.h, dof_chains.h, evaluate.h

Unfortunately, the actual release number is not present in any of the
header files, and therefore it would be difficult to distinguish any
of the V3 release candidates from the final V3 release. Examining the
version number in the pc files would be an option, as Christoph
already pointed out. In this respect it would also be important
(provided one has the ambition to present useful error messages to the
person trying to install Dune) to check for the mere presence of the
pc-files which were added quite late in the series of the V3 release
candidates (after Christoph had asked for this feature).

Best,

Claus
