I'll work on separate parsers for each of those, I am going through the
shlex library too. I'll let you know what I come up with.
BTW, thats even more reason to have wrappers for the read and write
functions. ;-)

No, it simply ignores the comments and empty lines and creates a dictionary
structure to display.
