%description
The uftrace tool is to trace and analyze execution of a program written in
C/C++/Rust. It was heavily inspired by the ftrace framework of the Linux kernel
(especially function graph tracer) and supports userspace programs. It supports
various kind of commands and filters to help analysis of the program execution
and performance.
