 /** Wrapper class for odocstream.
-    This class helps ensuring that no blank lines may be inadvertently output.
-    Use the special variables "breakln" and "safebreakln" as if they were
-    iomanip's to ensure that the next output will start at the beginning of
-    a line. Using "breakln", a '\n' char will be output if needed, while
-    using "safebreakln", "%\n" will be output if needed.
-    Use countLines() to retrieve the number of \n output since previous call.
+    This class is used to automatically count the lines of the exported latex
+    code and also to ensure that no blank lines may be inadvertently output.

+    they were iomanip's to ensure that the next output will start at the
+    beginning of a line. Using "breakln", a '\n' char will be output if needed,
