| 1to2 naively converts source code files from NAN 1 to NAN 2. There will be erroneous conversions, | |
| false positives and missed opportunities. The input files are rewritten in place. Make sure that | |
| you have backups. You will have to manually review the changes afterwards and do some touchups. | |
| ```sh | |
| $ tools/1to2.js | |
| Usage: 1to2 [options] <file ...> | |
| Options: | |
| -h, --help output usage information | |
| -V, --version output the version number | |
| ``` | |
