1//! `proc orphans` - Find orphaned processes
2//!
3//! Examples:
4//!   proc orphans              # List orphaned processes
5//!   proc orphans --in .       # Orphans in current directory
6//!   proc orphans --by node    # Only those named node (--cmd: node anywhere in the command line)
7//!   proc orphans --kill       # Find and kill orphans
8//!   proc orphans --kill --yes # Kill orphans without confirmation
