+I've reviewed this plugin's code, and there is one major issue with it,
+namely this line:
+
+	system("hnb '$params{page}.hnb' 'go root' 'export_html $tmp' > /dev/null");
+
+This could potentially allow execution of artibtary shell code, if the filename
+contains a single quote. Which ikiwiki doesn't allow by default, but I prefer
+to never involve a shell where one is not needed. The otl plugin is a good
+example of how to safely fork a child process without involving the shell.
+
+Other problems:
+
+* Use of shell mktemp from perl is suboptimal. File::Temp would be better.
+* The htmlize hook should not operate on the contents of `$params{page}.hnb`.
+  The content that needs to be htmlized is passed in to the hook in
+  `$params{content}`.
+
+If these problems are resolved and a copyright statement is added to the file,
+I'd be willing to include this plugin in ikiwiki. --[[Joey]]
