-The plugin is available at <http://www.schwinge.homeip.net/~thomas/tmp/texinfo.pm>.
+This plugin is not neccessarily meant to enable people to write arbitrary
+wiki pages in the Texinfo format (even though that is possible, of course),
+but rather to ease collaboration on existing Texinfo documents.
+
+The plugin is available at

 It's very basic at the moment, but will be improved over time.

-ikiwiki (obviously) doesn't understand (parse) the copyright and licensing
-statements which are included in `.texi` files.
+There needs to be some logic to establish a mapping between the *N* input files
+and the *M* output files.
+(At least for web-editing via CGI this is needed: ikiwiki (currently) needs to be able
+to deduce *one* input file from a given output file)
+Easiest would be either to have *N = 1*
+(plus perhaps some input files that are not meant to be editable, like `gpl.texi`)
+or to have
+*M = N* and have a (?) one-to-one mapping between *input file n* and *output file m*
+(which is not possible in Texinfo's `makeinfo` at the moment).

 ## `makeinfo` Output
 
 `makeinfo --html` is being used for rendering.  It creates stand-alone
 HTML files, while ikiwiki only needs the files' `<body>`s.

+# Bugs
+
+## Non-functional Texinfo Commands
+
+Those commands are know to not work currently:
+
+* `@printindex`
+* `@shortcontents`
+* `@contents`
+
+This is due to `makeinfo` not providing this functionality if rendering to stdout.
