      3 # Test texinfo.tex changes by running various manuals through with an
      4 # old version, saving the .ps result from dvips, doing the same with a
      5 # new version, and comparing.  Idea from Stepan Kasal.
      6 # 
      7 # Another option is to run the manuals all the way through using
      8 # texi2dvi, which tests in another way.
