Dreamhack : question about structure of directory

[namanhams]

Hi ,

According to here wiki.dwscoalition.org/notes/Main_development_folder  :  "anything that appears at http://www.dreamwidth.org/filename.bml will be here, as htdocs/filename.bml" 

But the link to the "Reading page" is :  "YourUserName.dreamwidth.org/read", which i can not find any "read" folder or "read.pl" file in the dw folder.

There are some similar links that i can not find the source file :

"YourUserName.dreamwidth.org/calendar" -> link to "Archive"
"YourUserName.dreamwidth.org/"   -> link to "Recent entries"
......


Please help to clarify for me. Thanks a lot.
