+The \''\%' command needs to be redefined for TeX4ht source files,
+but this redefinition causes compilation errors when it is used in
+titles or captions. So we redefine it to the original LaTeX
+definition. We can detect if we are in the literate sources by checking 
+if the \''\MAKETITLE' command is defined.

+I don't know what this code is supposed to do, but it can produce
