ctensor is the analog of grtensor in maxima. The basic operations with
tensor's componets available in both packages are comparable and they have
the similar syntax (I guess grtensor itself was inspired by macsyma/reduce
packages). Though grtensor lacks indicial manipulation ability. The
mentioned web-site has a lot of nice tests which are worth to repeat with
Maxima
