electron updater
A script for updating binary hashes.
It supports the following modes:
| Mode | Description |
|------------- | ----------------------------------------------- |
| `update` | for updating a specific Electron release |
| `update-all` | for updating all electron releases at once |
The `update` command requires a `--version` flag
to specify the major release to be update.
The `update-all` command updates all non-eol major releases.
The `update` and `update-all` commands accept an optional `--commit`
flag to automatically commit the changes for you.
