+	uses just two simple functions:
+
+	void RepairBoards()
+		- finds or repairs errors in the database to fix possible problems.
+		- requires the admin_forum permission.
+		- uses the raw_data sub template.
+		- calls createSalvageArea() to create a new board, if necesary.
+		- accessed by ?action=admin;area=repairboards.
+
+	void pauseRepairProcess(array to_fix, string current_step_desc, int max_substep = none, force = false)
+		- show the not_done template to avoid CGI timeouts and similar.
+		- called when 3 or more seconds have passed while searching for errors.
+		- if max_substep is set, $_GET['substep'] / $max_substep is the percent
+		  done this step is.
+
+	array findForumErrors()
+		- checks for errors in steps, until 5 seconds have passed.
+		- keeps track of the errors it did find, so that the actual repair
+		  won't have to recheck everything.
+		- returns the array of errors found.
+
+	void createSalvageArea()
+		- creates a salvage board/category if one doesn't already exist.
+		- uses the forum's default language, and checks based on that name.
