* manage 404: Display better errors.
* alt texts on pre and quote?
* a way to get the source of a page, using urlrewriting

* On links indicate whether it's on Gemini or Www or image.

* Page menu on upper and lower sides: [parent dir] [root dir] [inline images] [raw response] [view cert] 
* Check unicode capability
* Manage different type of carriage return: CR CR/LF LF
* Do not output an empty line for the last carriage return of the document
* Test on a shared hosting
* Be able to navigate (custom the links) when using htmgen.php?url=…
* Text localisation
* Search all cases where a narrow no-break space would apply
* Manage logging (cache refresh, debug)
* Split the main loop in two: one part to decode the text to internal language, the other to make the HTML
* Something to build gmi files and connect it afterwards to generate HTML : Abstract --> gemtext --> HTML. This would allow to make services output on both Gemini and HTML.
