thank you!

actually, i was stuck with the url design for a while, i enable PTL and i
have a RootDirectory class, so i can write index page by the _q_index(), and
use _q_export[] to involve other page, the url is like: http://localhost/
http://localhost/other/ , but what about i
http://loalhost/other/otherother/.../... , and the otherother/... parts are
erratic. _q_export[] can't do this, and if i want make my code structured, i
must put the code in multi-files and the files in multi-folders, like admin
pages in folder"admin", userinterface pages in folder "interface", but
there's only one RootDirectory and one _q_index() method i've wrote, does
every folder need a RootDirectory class?
many many questions in my head, now i can learn some examples first :)
