-# Textual representation of the cube
-
-The functions readcube() and writecube() use different formats to read
-and write a cube to text. Not all formats are supported for both input
-and output.
-
-## H48 - standard format for h48 (read, write)
-
-Each edge is represented by two letters denoting the sides it belongs to
-and one number denoting its orientation (0 oriented, 1 mis-oriented).
-Similarly, each corner is represented by three letters and a number
-(0 oriented, 1 twisted clockwise, 2 twisted counter-clockwise).
-Edge orientation is relative to the F / B axis, corner orientation is
-relative to the U / D axis.
-
-The pieces are ordered such that the solved cube looks like this:
-
-UF0 UB0 DB0 DF0 UR0 UL0 DL0 DR0 FR0 FL0 BL0 BR0
-UFR0 UBL0 DFL0 DBR0 UFL0 UBR0 DFR0 DBL0
-
-Whitespace (including newlines) between pieces is ignored when reading
-the cube, and a single whitespace character is added between pieces
-when writing.
-
-The cube after the moves R'U'F looks like this:
-
-FL1 BR0 DB0 UR1 UF0 UB0 DL0 FR0 UL1 DF1 BL0 DR0
-UBL1 DBR1 UFR2 DFR2 DFL2 UBL2 UFL2 DBL0
-
-## SRC - representation of the object in C code for cube_array (write)
-
-The exact format depends on the internal cube representation. It is
-guaranteed that, if OUT is the output in this format, the line
-
-cube_t cube = OUT;
-
-is interpreted correctly by h48.
