tool: D48:  usage : 

tool: D117:  (1)   %s [option] mat


tool: D13:  (2)   %s [option] - 



tool: D109:  options can be:

tool: D4:    -n : convert from new format to old format. [default: old to new]

tool: D53:    -f : convert from new format to old format compatible to FL implementation. [default: old to new]

tool: D62:    -s : sorts the row by weight (smallest first) [default : enabled, new format only]

tool: D124:    -S : don't sort the rows by weight (smallest first) 

tool: D24:    -r : reverts order [default : enabled, new format only] 

tool: D1:    -R : don't revert order 

tool: D59:  (1) will produce a file on stdout from matrix mat

tool: D50:  (2) will produce a file on stdout from  stdin 

tool: D145:  this would happen like : zcat mat.gz | %s mat - > mat.gbm


tool: D5:  Warning : the input matrix has to be in the correct format

tool: D73:  Warning : new matrix format is suffixed by .gbm (but not necessary)
