List of files to be used with Mathematica, version 2.2
both MS_DOS  and WINDOWS notebooks supported.

IMPORTANT WARNING: For the programming of applications it is not allowed
to use the alias in the files to be read by Mathematica. For instance, a
file to be read cannot contain  CF[...] but CommonFactor[...].
The simplifying aliases can only be used in interactive session.

A special care with ** featuring the Clifford product CP. This alias is
only allowed in interactive session after having effected the instruction
PreReadOn[] .

Many files do contain comments and instructions for usage, so we merely
list here its size and contents:

CLIFFORD M           9,947   The general algebraic package
CLIFFTOT M          12,547   General algebraic+differential package

DIRACNEG LOG        39,893   Files related to the Dirac-Hestenes equivalence
DIRACNEG M           2,778   in both signatures.  For MSDOS  *.log are the
DIRACNEG MA        106,303   outputs produced by *.m. 
DIRACPOS LOG        40,380   For Windows use *.ma
DIRACPOS M           2,770 
DIRACPOS MA        106,394 

INERTIA  M           7,281   D. Hestenes table on Inertia tensors in NFCM 
INERTIAC M          23,829   The same with Clifford products performed
INERTIAN M           6,802   Numerical examples, misprints warnings!

INREG3   M             689   Files helpful to generate regular representations
INREG4   M             942   in dimensions 3,4,5,6
INREG5   M           1,511 
INREG6   M           2,507 

MANUAL.MA           75,320   A Mathematica notebook that introduces the 
                             use of the package clifftot.m

NABLA    M           3,685   The general differential package

RODVAZ   CAR       103,833   Files related to a well-known "non-null" solution
RODVAZ   SPH         2,191   of Maxwell vacuum equations, recently presented
RODVAZ1  M           5,583   by W. Rodrigues and J. Vaz.   
RODVAZ1  MA        300,136   1 refers to Cartesian treatment, 2 to spherical
RODVAZ1R MA         44,214   1R is the reduced version, without the last,
RODVAZ2  M           4,685   huge output that evaluates to zero
RODVAZ2  MA         28,299   Same comments as with Dirac-files.

README   DIR         2,267   same as readme.txt (as submitted by the authors)
                             but without the bibliographical information shown
                             on top

README   TXT         3,736   this file

jmparra1.zip        55,531   the first out of two .zip files with some of the
                             above files
jmparra2.zip        98,389   the second out of two .zip files with the remaining
                             files

NOTE: rather than transferring the above files one by one, just download the
      two BINARY files jmparra1.zip and jmpara2.zip, and use pkunzip to unzip
      them.  You will then find all the files decribed above (some 70+) from 
      'clifford.m' to 'readme.dir'.  
      
      File readme.txt is not part of the two .zip files.
