Description:
   GRG 3.2 is the computer algebra system designed for the calculations
   in differential geometry and field theory. GRG is based on the
   computer algebra system REDUCE but has its own simple input language.
   GRG works with tensors, spinors, vectors, differential forms.
   GRG knows the covariant properties of the objects: one can
   raise and lower indices, compute covariant and Lie derivatives,
   perform coordinate and frame transformations etc. GRG has more
   than 150 built-in standard field-theory and geometrical
   quantities and formulas for their computation providing ready
   solutions to many standard problems.
