53   -b buildstats The path where the folder resides
55   -n N          Top N recipes to display. Ignored if -S is present
57   -r recipe     The recipe mask to be searched
58   -t tasks      The tasks to be computed
60   -s stats      The stats to be matched. If more that one stat, units
61                 should be the same because data is plot as histogram.
62                 (see buildstats.sh -h for all options) or any other defined
65   -a            Accumulate all stats values for found recipes
66   -S            Sum values for a particular stat for found recipes
67   -o            Output data file.
