This module provides the user interface for the percept data collection (profiling).
Equivalent to start(Filename, [procs]).
Starts profiling with supplied options. All events are stored in the file given by Filename. An explicit call to stop/0 is needed to stop profiling.
Starts profiling at the entrypoint specified by the MFA. All events are collected, this means that processes outside the scope of the entry-point are also profiled. No explicit call to stop/0 is needed, the profiling stops when the entry function returns.
