I found that part of the functions of itensor does not work within cvs
version of maxima and even in the last release 5.9.3. They are mostly
concerned about Levi-Chevitta tensor. Some tests can be found at
tensor/tests/itest.mac. The code of the package was not changed since last
year. Everything was ok for 5.9.2 and for cvs versions dated to the very
begining of this year (at least begining of Jan). What can be a problem?
best regards,
Valery
