  16 DESCRIPTION
  17 -----------
  18 The http://lttng.org/[_Linux Trace Toolkit: next generation_] is an open
  19 source software package used for correlated tracing of the Linux kernel,
  20 user applications, and user libraries.
  21
  22 LTTng consists of Linux kernel modules (for Linux kernel tracing) and
  23 dynamically loaded libraries (for user application and library tracing).
  24
  25 The _`lttng-crash`_ command-line tool is used to recover and view
  26 LTTng trace buffers in the event of a system crash.

  29 OPTIONS
  30 -------
  31 option:-x 'PATH', option:--extract='PATH'::
  32     Extract recovered traces to path 'PATH'; do not execute the trace
  33     viewer.
  34
  35 option:-v, option:--verbose::
  36     Increase verbosity.
  37 +
  38 Three levels of verbosity are available, which are triggered by
  39 appending additional `v` letters to the option
  40 (that is, `-vv` and `-vvv`).
  41
  42 option:-e 'VIEWER', option:--viewer='VIEWER'::
  43     Use trace viewer 'VIEWER' to view the trace buffers. 'VIEWER' is the
  44     absolute path to the viewer command to use, and it can contain
  45     command arguments as well. The trace directory paths are passed to
  46     the 'VIEWER' command as its last arguments.
  47 +
  48 Default: `babeltrace`.
