.BR "\-\-subbuf-size SIZE"
Subbuffer size in bytes {+k,+M,+G}.
Maximum size of each tracefile within a stream (in bytes).

.BR "\-W, \-\-tracefile-count COUNT"
Used in conjunction with \-C option, this will limit the number of files
Maximum size in bytes of the snapshot. The maxium size does not include the
metadata file. Human readable format is accepted: {+k,+M,+G}. For instance,
\-\-max-size 5M

+The minimum size of a snapshot is computed by multiplying the total amount of

+fairness between channels when extracting data.

.BR "\-C, \-\-ctrl-url URL"
Set control path URL. (Must use -D also)
