2011-05-21 to 2011-05-29

Communicated with mg and mpm on IRC and mailing list, and got the idea to relealise the issue 2084. Several patches before has been abandoned, and two of them are commited in http://hg.intevation.org/mercurial/crew/rev/59853c30e31e and http://hg.intevation.org/mercurial/crew/rev/ff4126ce9301. Afetr got some advice from mg, I will refactor my patch on getting a subsection help.

Besides, from this day on, I will use this page as my GSOC blog, and the old blog is too slowly to update.
