+===== Comparing and normalising documents =====
+Use this to compare PDF and word documents:
+  * Same the word document as plain text
+  * Use ''pdftotext'' to convert the PDF to plain text
+Use this Perl script to normalise each file:
+  my $str = do { local $/; <STDIN> };
+  # Strip paragraph numbers
+  $str =~ s/^[0-9.]+/\n\n/mg;
+  # Remove wrapped lines that are not paragraph separators
+  $str =~ s/(?<!\n)\n(?!\n)/ /g;
+  # Strip space at beginning of lines
+  $str =~ s/^\h+//mg;
+  # Normalise paragraph breaks
+  $str =~ s/\v\v+/\n\n/g;
+Compare both files using ''git diff --word-diff=color''
