title: Merge PDF files command line with bookmarks
body: <p>I am trying to accomplish a simple task of merging PDF files to one PDF. And I want the resulting PDF file to have Bookmarks to each file from the filename. And preferably i would like to have a free solution for this. </p>
  
  <p>I am on a windows system and want to execute this from either command line or even better from MSSQL. </p>
  
  <p>The thing is that i will create PDF files of orders from an ERP system with Crystal Reports. An stored procedure will create these PDF files. After that i want to take selected PDFs and create a new merged PDF of those and the merged PDF should have each order number (from the filename) as a bookmark. So that you easily can jump to an order number if you are searching for a specific one.</p>
  
  <p>And as I said preferably free solutions, if not available I am ready to code my own merge program in for example C# or similar.</p>
