Loading directory meta information from file

[yegle]

Just like extracting the title from wiki pages as the HTML title, I want to have a special file in a directory to provide meta information of this directory.

something like this:

| 
`-- directory_name
    `-- .meta

in system/.meta file:

title: "This_is_used_when_link_to_this_directory"
descrpiton: "We can display this text in the directory's index.html page, make this index page more informative"
