Integrated debugging commands

Cosmopolitan binaries can use debug tools integrated in the executable when you pass theses commands:

--strace: will print the system calls made by the executable. More info.

--ftrace: will analyze and debug kernel activities, offering functions such as latency tracing and event tracing to identify and address performance issues and understand specific kernel behaviors. More info.
