// Package main demonstrates distributed tracing across processes using programmatic management.
// It showcases how to:
// 1. Create and manage processes using gproc
// 2. Propagate trace context between processes
// 3. Execute shell commands with context
// 4. Handle process errors and logging
//
// This example uses gproc for programmatic process management and control.
