%description
s6 is a small suite of programs for UNIX, designed to allow process supervision
(a.k.a service supervision), in the line of daemontools and runit, as well as
various operations on processes and daemons. It is meant to be a toolbox for
low-level process and service administration, providing different sets of
independent tools that can be used within or without the framework, and that can
be assembled together to achieve powerful functionality with a very small
amount of code.

%changelog
* Tue Aug 25 2026 Inga Vesnova <inga.vesnova@gmail.com> - 2.15.1.0-1
- Applied x86-64-v2, -O2, LTO, and lld optimizations
- Fixed configure flags to pass CFLAGS/LDFLAGS correctly to skarnet build system
- Added chrpath to clean up standard RPATHs (including %{_libexecdir})
- Explicitly excluded man pages and documentation for a minimal package size
- Added explicit versioned BuildRequires and Requires for skalibs-devel and execline-devel
