+ * QUICK START GUIDE
+ * =================
+ * MatitaWeb is a web interface for the Matita interactive theorem prover.
+ * Its user interface is composed of two main panes:
+ *
+ * -> the script area, whose content you are currently reading, which is
+ * used to input definitions and theorems to be checked by Matita;
+ * -> a top area with a title bar and a toolbar providing all the
+ * interactive operations apart from proof authoring.
+ *
+ * The toolbar on the top is divided in two sections:
+ * -> the large blue tiles provide the basic operations concerning the
+ * execution and checking of a proof script, including step-by-step
+ * execution
+ * -> the smaller circular buttons on the right provide script management
+ * operations (create, open, save...)
+ *
+ * \ 5img class="topimg intext" src="icons/advance.png"\ 6 Advance - executes the next step of the script
+ * \ 5img class="topimg intext" src="icons/retract.png"\ 6 Retract - undoes the execution of the last step of the script
+ * \ 5img class="topimg intext" src="icons/top.png"\ 6 Top - undoes the whole script, returning to the start
+ * \ 5img class="topimg intext" src="icons/position.png"\ 6 Play - executes the script until the current position of the cursor
+ * \ 5img class="topimg intext" src="icons/bottom.png"\ 6 Bottom - executes the whole script, until the end (or an error) is reached
+ *
+ * \ 5img class="toolbarimg intext" src="icons/add.png"\ 6 New script - creates a new empty script, opening a window to specify where
+ * the script should be placed in the library
+ * \ 5img class="toolbarimg intext" src="icons/folder.png"\ 6 Open script - opens an existing script in the library
+ * \ 5img class="toolbarimg intext" src="icons/save.png"\ 6 Save script - saves the current script
+ * \ 5img class="toolbarimg intext" src="icons/saveas.png"\ 6 Save script as - saves the current script with a new name
+ * \ 5img class="toolbarimg intext" src="icons/upload.png"\ 6 Import local script - allows the user to import a script from the local
+ * machine into the web interface buffer
+ * \ 5img class="toolbarimg intext" src="icons/check.png"\ 6 Commit - commits user changes to the shared library
+ * \ 5img class="toolbarimg intext" src="icons/refresh.png"\ 6 Update - synchronizes the user working copy by updating it with the
+ * changes in the shared library
+ * \ 5img class="toolbarimg intext" src="icons/questionmark.png"\ 6 Show log - shows the last warnings/error messages (for debugging purposes)
+ * \ 5img class="toolbarimg intext" src="icons/delete.png"\ 6 Delete hyperlinks - removes all hyperlinks from the script
+ *
+ * If you are new to Matita and/or interactive theorem proving, we have a
+ * tutorial in 10 parts for you. To load it:
+ * 1) click on the "Open script" button in the toolbar (the second circular
+ * button, whose icon shows a folder)
+ * 2) in the dialog box, select the "tutorial/chapter1.ma" script, then
+ * press OK (scripts chapter2.ma ... chapter10.ma contain more advanced
+ * examples that the user is encouraged to try after chapter1.ma)
+ * 3) follow the instructions in the script.
+ *
