+Special Filtering Region
+========================
+  A region like below will be passed to external filter command.
+     %#BEGIN FILTER{foo.pdf}{dot -T %t -o %o}
+     \if0
+     ....blah blah blah...
+     ....blah blah blah...
+     ....blah blah blah...
+     \fi
+     %#END
+
+In this case, typing `[prefix] t e' send three `blah' lines
+to "dot -T pdf -o foo.pdf" as standard-input.  It is useful to
+have source of text-origin graphic generated by such tools as
+graphviz or blockdiag, in LaTeX source.  This special form of region
+can be inserted via feeding `.dot' into environment completion by
+`[prefix] t b'.

+
+;;; Commentary:
+;;;
+;;;	This lisp enables passing inline text to some external filter
+;;;	command to generate files such as graphic files.
+;;; 
+;;;	Typical situation is using blockdiag/dot(graphviz) command to
+;;;	generate png/pdf file.
+;;;
+;;; Example:
+;;;
+;;;	[[LaTeX Source]]
+;;;	%#BEGIN FILTER{foo.pdf}{dot -T %t -o o}
+;;;	\if0
+;;;	===
+;;;	digraph {
+;;;	  A -> B;
+;;;	  B -> C;
+;;;	}
+;;;	===
+;;;	\fi
+;;;	%#END
+;;;	\includegraphics{foo.pdf}
+;;;
+;;;	In this  case above, when  you type  `[prefix] t e'  between two
+;;;	`===' lines, the  content in a region are fed  to dot command as
+;;;	follows:
+;;;	
+;;;	    echo TEXT | dot -T pdf -o foo.pdf 
+;;;
+;;;	Then foo.pdf file will be generated and the image (as PNG) will
+;;;	be displayed in the next window.
