Give statistical analysis of the paje trace

$0 [ options ] paje.trace [paje.trace2 ...]

Options:
   -r      To fix range x1:x2 ("-1" for infinity)
   -n      To choose a certain state
   -v      Print output to command line
   -h      Show this message

Examples:

$0 -n chol_model_22 example.native.trace

$0 -r 100:300 -n FetchingInput,Overhead -v example.native.trace example.simgrid.trace
