59# Run in interactive mode

61
62# Run with debug logging
63crush -d
64
65# Run with debug logging in a specific directory
66crush -d -c /path/to/project

69crush -D /path/to/custom/.crush
70
71# Print version
72crush -v

74# Run a single non-interactive prompt
75crush run "Explain the use of context in Go"
