Subject: runlttv: Add options to specify LTTV options
X-Git-Tag: v0.12.20~20
X-Git-Url: https://git.lttng.org/?p=lttv.git;a=commitdiff_plain;h=697977bbabfda699894a1a5d921214191a9b31d9

runlttv: Add options to specify LTTV options

It is possible, from .runlttvrc:
* to modify the list of modules loaded in text mode or in graphical mode while
  still honoring the mode specified in the runlttv command line
* to change the default mode while still honoring the mode specified in the
  runlttv command line

from the command line or .runlttvrc:
* force the mode
* specify traces
* specify options that go before (eg. -v) or after (eg. -h) the list of
  modules
