Initial value:

= "\
This program computes cubical homology groups and homology generators.\n\
The ring of coefficients is Z or Z_p (the integers modulo prime number p).\n\
Call with:\n\
filename - the name of a file that contains a list of cubical cells,\n\
Switches and additional arguments:\n\
filename2 - the name of an additional file for relative (co)homology;\n\
-pN - selection of the coefficients: p=0 for Z, p>1 for Z_p (default: 0);\n\
\tnote: one should use p <= 181,\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\
-w N1,..,Nk - set space wrapping, a.k.a. periodic boundary conditions;\n\
\trepeat the n-tuple for each dimension n; use 0 for no wrapping,\n\
-dpi, -dincl, -dphi - display the computed maps: pi, incl, phi,\n\
-dd - display the boundary map in the minimal model (the nontrivial part),\n\
--verify - do additional verification of the computed maps,\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\
