The documentation is taken from a file called Grammar.pgf_info, located
next to the Grammar.pgf file on the server.
The first line of the documentation is displayed below the menu bar in
the minibar. The rest of the documentation is displayed when you press
the "More info" button (or the "i" button).
The documentation can contain HTML markup. Blank lines are treated as
paragraph breaks.
After pressing the "i" button to view grammar info, there is now a
"More info" button to get more detailed information about all categories and
functions in the grammar.
The minibar is now displayed inside the editor, intead of on a separate page.
This makes the context clearer and makes it more obiovous how to return to the
editor.
"gf -server" mode now contains everything needed to run the minibar and
the grammar editor (including example-based grammar writing).
The Setup.hs script installs the required files where gf -server can find them.
These files have been moved to a new directory: src/www.
The separate server program pgf-http is now obsolete.
