We're using INI in our app, turned out to be quite simple, like this:
[eal]
;; EAL common options:
;; -c COREMASK Hexadecimal bitmask of cores to run on
# coremask = fff
;; -l CORELIST List of cores to run on
corelist = 3,4,5
;; --lcores COREMAP Map lcore set to physical cpu set
; coremap =
;; --master-lcore ID Core ID that is used as master
; master-lcore-id = 0
;; -n CHANNELS Number of memory channels
memory-channels = 4
