# HTML serializer example
This example shows a minimal application that serializes a HTML file
and writes it to standard output.
## How to build
If using `make(1)`, just run `make` from this directory.
If using CMake, examples are built by default when configuring the project
from [the top-level `CMakeLists.txt`](../../CMakeLists.txt).
## How to run
Run the executable without any command line arguments. The following text
should be written to the standard output:
```
<html>
<head>
<meta charset="UTF-8"/>
</head>
<body>testing slweb</body>
</html>
```
