(description
"This package provides drop-in replacements for the base @code{system2()}
function with fine control and consistent behavior across platforms. It
supports clean interruption, timeout, background tasks, and streaming STDIN /
STDOUT / STDERR over binary or text connections. The package also provides
functions for evaluating expressions inside a temporary fork. Such
evaluations have no side effects on the main R process, and support reliable
interrupts and timeouts. This provides the basis for a sandboxing
mechanism.")
