======Comparing the text in two PDF files======
Need to compare the text in two PDF files to find differences?

Try the following (for Windows):
  - Download [[http://www.foolabs.com/xpdf/download.html|Xpdf]] for pdftotext.exe.
  - Download [[http://unxutils.sourceforge.net/|GNU utilities for Win32]] for diff.exe.
  - Extract the text from the PDF files while preserving the layout with:<code>pdftotext -layout file.pdf</code>
  - Determine the differences and store these side by side (-y) in a text file with:<code>diff -y --width=220 file1.pdf file2.pdf > file1_file2_diff.txt</code>
    - You might need to test different settings for the value after --width= to prevent lines from being terminated prematurely.
  - Open file1_file2_diff.txt to look at the differences.
