Initial value:

= "\
This program computes and displays all the non-zero Steenrod squares\n\
of a cubical set. A formula introduced by P. Real and co-authors is used\n\
for a simplicial set into which the cubical set is first subdivided.\n\
Note that the ring of coefficients is fixed to Z_2.\n\
Call with:\n\
filename - the name of a file that contains a list of cells for the test,\n\
Switches and additional arguments:\n\
filename2 - the name of an additional file for relative (co)homology;\n\
-r - compute reduced homology (with the empty set as a cell of dim -1),\n\
-b - don't add boundary cells (use -bx and -ba for X and A selectively),\n\
--log filename - save the output to a file (without progress indicators),\n\
--quiet - suppress data output to the screen (whcih can be still logged),\n\
--help - display this brief help information only and exit.\n\
For more information please consult the accompanying documentation\n\
or ask the program's author at http://www.PawelPilarczyk.com/."
