Two pdfs in one

Yesterday I wanted to concatenate two pdfs into one. Specifically, I had my BYU transcript and my UofU transcript and I wanted to put them together in a single transcript. This ended up being a fairly easy process.

1. Open up the files
   
2. Print the files (pdf or html) to a file. This should create postscript (.ps files)
   
3. Combine the postscript files using psmerge -ooutput.ps input1.ps input2.ps
   
4. Run ps2pdf13 output.ps
   

Then you have output.pdf which has both of the original files in it!
