/** 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.
+ To this end, use the special variables "breakln" and "safebreakln" as if

+ The class also records the last output character.
