procutils-skill 0.2.0

//! Live-process tests for `skill`. skill is largely a thin wrapper
//! over the same selector + signal infrastructure as pkill, but it
//! takes free-form expression args (PIDs, usernames, ttys, command
//! names) rather than a regex pattern.
//!
//! Skipped automatically on systems without unprivileged user + PID
//! namespaces (some sandboxed CI runners).
