PowerShell Requires Chilkat v11.7.0+

PDF Placeholders with Other Delimiters: [[name]]

Demonstrates the "placeholderSyntax" option. Placeholders are {{name}} by default; a template written with other delimiters, such as [[name]] or <>, says so with placeholderSyntax, written around the word "name".
