A customer just asked for our FogBugz 6.0 documentation posted here in one PDF file.  I'm certain there are better ways of doing this (like having whatever generates our docs, actually generate the pdf) I sought out a quick and dirty solution that will work for any section of a website that you want to save to PDF.

1. Install CutePDF which allows you to print anything to pdf.   Any web page (including any FogBugz web page) can be exported to PDF by just hitting "Print".
2. Run Internet Explorer and nagivate to the website you want to save to PDF.  File->Print, and choose the Options tab where it lets you select the checkbox to "Print all linked documents"
3. Save all the PDFs in a new folder.
4. Download PDFtk to that folder.  This is a command line tool that will merge your pdf files together.  Run it like so 'pdftk *.pdf output MergedPDF.pdf'

Here's the resulting FogBugz 6.0 Documentation PDF: FogBugzDocumentation60.pdf (2.75 mb)

Update: A reader just pointed out PrimoPDF is also free and has the option to "append" to an existing PDF doc, removing the extra step above.  Thanks!
