+SPELLCHECK: 
+One way to do a spell check on the final document,
+and to get a simple text output to look for word repeats
+is to do the following (assuming you have the necessary
+tools):
+   # -enc Latin1 to avoid utf8, we do not need utf8 here.
+   pdftotext -enc Latin1 dwarf5.pdf
+   # Now you have dwarf5.txt
+   # The _ are not understood by spell
+   sed -e 's/_//g' <dwarf5.txt >dwarf5.txt2
+   # Let upper and lower case compare equal
+   spell dwarf5.txt2 |sort -f |uniq -i
+
 CAUTION: 
 The tools don't really do parsing and
 the lexical processing is barely adequate for the task.
