-## OVERVIEW
-## This program is part of the rubikrotation package, and is complementary to
-## the LaTeX rubikcube package. It processes Rubik rotation sequences on-the-fly.
-## The program reads a datafile (rubikstate.dat) output by the rubikcube package
-## and writes the new state to the file rubikstateNEW.dat, which is then input
-## by the TeX file. Further documentation accompanies the rubikrotation package.
-
-## Note that all posible state changing rotations of a 3x3x3 cube are
-## either conbinations of, or the inverse of, just 9 different rotations,
-## three associated with each XYZ axis.
-##--------------------------------------------------
-
-##=============main===================================================
-
-## This main module opens three files, and
-## sets up an array for collecting all errors (%error), and sets an error flag to "",
-## reads in the rubik state data file =rubikstate.dat (output by TeXfile),
-## and calls subs to write the TeX_OUT_FILE,
-## and finally closes all files.
-## Each line of the input file consists of a comma separated list of arguments.
-## The first argument in each line of the file rubikstate.dat is the rubikkeyword.
-## Program is documented in the rubikrotation.pdf (see section ``Overview'')
-
-### start by opening the three working files (last one ``for append'')

-##================================================
-## The following 9 (90 degree) rotation transformations are used
-## to generate all the rotations used in the `rotation sub'
-## each of these is a permutation for both colours and numbers
-## of the cubie facelets.
-## The following 9 subroutines are named as follows:
-## (about X-axis) rrR, rrSr, rrLp
-## (about Y-axis) rrU, rrSu, rrDp
-## (about Z-axis) rrF, rrSf, rrBp
-## see the rubikcube package documentation for full details regarding
-## rotation notation and commands.
-## METHOD & NOTATION
-## each sub (below) starts by making an array[0] for the cubie colour
-## and an array[1] for the cubie number.
-## Each of the face rotations (rrR, rrLp, rrU, rrDp, rrF, rrBp) is involved with
-## two pairs of connected but different permutations/transformations as follows:
-## (a) one pair for the 12 Side cubies (arrays = @Xs0 (for Side colours), @Xs1 (for Side numbers)), and
-## (b) one pair for the 9 Face cubies (arrays = @Xf0 (for Face colours), @Xf1 (for Face numbers)).
-## Each of the center slice rotations (rrSr, rrSu, rrSf) is involved with just one pair of
-## permutations for the 12 Side cubies (arrays = @Xs0 (for Side colours), @Xs1 (for Side numbers)).
-## We document only the side and face of the first sub (rrR) in detail, since the other subs are of similar form.
