Gallery generator for Phugo

For each directory in content it generates or updates the _index.md file with the list of all JPG files in the directory.

If _index.md already exists, it's metadata will be kept, the rest is overwritten.

If the metadata of the _index.md file contains manual: true, the directory is ignored.

The thumbnails must be named by the original name prefixed by _th_.

const fs = require('fs');

fs.readdirSync('content')
  .filter(entry => fs.statSync(`content/${entry}`).isDirectory())
  .forEach(dir => {
    let files = fs.readdirSync(`content/${dir}`)
      .filter(file => file.endsWith('.jpg'))
      .filter(file => !file.startsWith('_th_'));
      
    let content;
    
    if  (fs.existsSync(`content/${dir}/_index.md`)) {
      const lines = fs.readFileSync(`content/${dir}/_index.md`, {encoding : 'utf8'}).split('\n');
      
      if (lines.indexOf('manual: true') !== -1) {
        return;
      }
      
      const headerEnd = lines.lastIndexOf('---');
