// to convert MS Office files to PDF and replace templated tags present in the document
// with content supplied via json
//
// For a detailed specification of the template format and supported features,

// This conversion is performed entirely within the PDFNet and has *no*
// external or system dependencies -- Conversion results will be
// the same whether on Windows, Linux or Android.
