| /* |
| * Binary used to on RunCommand tests. |
| * |
| * Usage: |
| * |
| * - Unless stated otherwise this command: |
| * |
| * 1.Prints `stdout\n` on `stdout` and flushes it. |
| * 2.Prints `stderr\n` on `stderr` and flushes it. |
| * 3.Exit with status 0. |
| * |
| * - If 1st argument is '--pid', it first prints its pid on `stdout`. |
| * |
| * - If 1st argument is '--uid', it first prints its uid on `stdout`. |
| * |
| * - If 1st argument is '--crash', it uses ALOGF to crash and returns 666. |
| * |
| * - With argument '--exit' 'CODE', returns CODE; |
| * |
| * - With argument '--sleep 'TIME': |
| * |
| * 1.Prints `stdout line1\n` on `stdout` and `sleeping TIME s\n` on `stderr` |
| * 2.Sleeps for TIME s |
| * 3.Prints `stdout line2\n` on `stdout` and `woke up\n` on `stderr` |
