refdb implements a few backends to output extended notes. You can select them with the -t option of the getnote command.
The screen backend provides the output most suitable for viewing notes in a terminal. Send the output through a pager for best results. Use the -s NL or -s ALL options to display all objects the note is linked to.
The information returned by this backend is encoded as a HTML document. Use this format to print nicely formatted notes from your web browser. Otherwise the same applies as said for the scrn backend. See above for some hints about formatting the output with a CSS file.
The output is the same as for the html backend but the output is formatted as an XHTML document according to the XHTML V1.0 Transitional DTD.
This backend encodes the output in xnote documents, the same as the input format for extended notes.
