1# share/pass: a program run on ez's own stdin, stdout and stderr, as `cargo run`
2# runs one. Every other program ez starts goes through snap's `exec`, which
3# hands the child /dev/null for stdin, holds what it prints until it exits,
4# and answers both at once; that is what a command that reads the answer
5# wants. `ez run` and `ez tool run` read nothing back: the program talks to
6# the person, and ez only waits for it and exits with its status (`S.code`
7# and `TP.code`, EZ-OUT-1).

11# the program and its arguments, newline separated, run with no shell between
12# and nothing captured. The answer is the status it exited with: 128 plus the
13# signal for one a signal ended, and 127 for one that could not be started.
