+
+
+		Process the FILENAME, and generate a full HTML page.
+
+		The FILENAME is used to infer the output URL, by removing the

+		`.html`.  This URL is used to build the self-referencing
+		"canonical" link, extracting plaintext snippets, etc.
+

+
+		  Generate the HTML for a pastebin:
+
+		    $ sh genhtml.sh src/content/a-paste.md > src/content/a-paste.html
