This batch analysis module can be invoked like this :
$ lttv -L path/to/lib/plugins -m batchAnalysis\ -t trace1 -t trace2 ...
It permits to call any registered action to perform in batch mode on all the trace set, which consists of the traces loaded on the command line. Actions that are built in the batchAnalysis module are statistics computation. They can be triggered by using the -s (--stats) switch.
However, the batchAnalysis module is mostly a backend for every other text module that does batch computation over a complete trace set.
