Sysprof is an open-source (GPLv3) whole-system profiler for Linux.
Reason for inclusion: Sysprof is a useful development tool; it can be used to profile almost any function in any program in terms of call percentage, battery usage, disk accesses, network usage, etc. It has special profiling support for the GTK stack. By default, Sysprof includes a CLI frontend and a GTK frontend.
I haven't found anything similar in the package repo. Additionally, Sysprof cannot be installed without root access (and so it should be a package, to avoid having to run sudo ninja install).
