21# Given a 'buildstats' path (created by bitbake when setting 21# Given 'buildstats' data (generate by bitbake when setting
22# USER_CLASSES ?= "buildstats" on local.conf) and task names, outputs 22# USER_CLASSES ?= "buildstats" on local.conf), task names and a stats values
23# '<task> <recipe> <elapsed time>' for all recipes. Elapsed times are in 23# (these are the ones preset on the buildstats files), outputs
24# seconds, and task should be given without the 'do_' prefix. 24# '<task> <recipe> <value_1> <value_2> ... <value_n>'. The units are the ones
25# defined at buildstats, which in turn takes data from /proc/[pid] files
