title: can git be used for version control on non text documents such as word doc or xls etc
body: <p>I've been learning about the GIT version control system recently and It seems to work very well for plain text documents as you can add a single line, go back and fork it, revise the document and remove the line you just added.</p>
  
  <p>I program mostly in excel and write documentation in word. Can GIT be used to manage versions of these files (obviously not the stuff inside the files, but the files themselves?)</p>
