This module provides a nicer interface to the \module{_hotshot} C module.
Hotshot is a replacement for the existing \refmodule{profile} module. As it's
written mostly in C, it should result in a much smaller performance impact
than the existing profile module.

to generate events for every source line, or just on function call/return. It
defaults to 0 (only log function call/return). The argument \var{linetimings}
specifies whether to record timing information. It defaults to 1 (store timing
