tool: D106:  usage : 

tool: D56:  (1)   %s [option] mat


tool: D36:  (2)   %s [option] - 



tool: D12:  options can be:

tool: D129:    -n : convert from new format to old format. [default: old to new]

tool: D122:    -f : convert from new format to old format compatible to FL implementation. [default: old to new]

tool: D136:    -s : sorts the row by weight (smallest first) [default : enabled, new format only]

tool: D65:    -S : don't sort the rows by weight (smallest first) 

tool: D63:    -r : reverts order [default : enabled, new format only] 

tool: D83:    -R : don't revert order 

tool: D101:  (1) will produce a file on stdout from matrix mat

tool: D117:  (2) will produce a file on stdout from  stdin 

tool: D86:  this would happen like : zcat mat.gz | %s mat - > mat.gbm


tool: D147:  Warning : the input matrix has to be in the correct format

tool: D91:  Warning : new matrix format is suffixed by .gbm (but not necessary)
