The "/docdir" page:
Show the files and subdirectories within a single directory of the
source tree.  This works similarly to /dir but with the following
differences:
- Links to files go to /doc (showing the file content directly, depending on mimetype) rather than to /file (which always shows the file embedded in a standard Fossil page frame).
 -  
The submenu and the page title is not shown. The page is plain.
 
The /docdir page is a shorthand for /dir with the "dx" query parameter.
Query parameters:
- ci=LABEL
 - Show only files in this check-in. If omitted, the "trunk" directory is used.
 - name=PATH
 - Directory to display. Optional. Top-level if missing
 - re=REGEXP
 - Show only files matching REGEXP
 - noreadme
 - Do not attempt to display the README file.
 - dx
 - File links to go to /doc instead of /file or /finfo.
