# Filename file input plugin for Embulk
TODO: Write short description here and build.gradle file.
## Overview
* **Plugin type**: file input
* **Resume supported**: yes
* **Cleanup supported**: yes
## Configuration
- **option1**: description (integer, required)
- **option2**: description (string, default: `"myvalue"`)
- **option3**: description (string, default: `null`)
## Example
```yaml
in:
type: filename
option1: example1
option2: example2
```
## Build
```
$ ./gradlew gem # -t to watch change of files and rebuild continuously
```
