includes.pug

//- Like PHP, we can include content of another file in a file.
//- If another file extension is `.pug`, then it's content will be compiled.
//- If another files is non-pug file, then it's content will be included as raw text.
//- If no file extenstion is given, `.pug` is automatically appended to the file name.
