Cactus

This release adds support for SGI Altix, Intel EM64T (and presumably
AMD64 as well), and Xbox, revamps the reduction interface to bring it in
line with the interpolation interface, tests parallel operation on MacOS
X, changes the Windows support to use the Cygwin Perl rather than the
ActiveState Perl, makes the method of lines thorn mainstream, and adds
many bug and documentation fixes.

This release allows thorns using aliased functions to require that there be a thorn providing the function. It also includes various code cleanups and bug fixes.

The boundary and symmetry interfaces have been reworked to make the distinction between physical boundary conditions and boundaries conditions from mesh symmetries clear. The support for external packages has been enhanced by adding new configuration possibility for modules to state an explicit dependency on a library containing a particular capability to be present. There are many bugfixes and minor feature enhancements.

Timelevel rotation scheme rationalised. Now compiles and runs under MacOS X. New NaN checking thorn. New optimised interpolator thorn. Preliminary function aliasing support. New HDF5 checkpoint file recombiner.

This release adds compilation updates on AIX and under cygwin, syntax enhancements in ccl files, bugfixes, support for HPVM and MPIPro mpi compilation out of the box, new arrangements with C jpeg and HTTPD thorns, and an IsoSurfacer which has been converted to C.
