+## 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.

+## the new position of Up-right-bottom (Urb) (side)facelet.
