Write this line in a buffer:

nisse = <totte>

and then run

 (let ((ebnf-syntax 'abnf)) (ebnf-print-buffer "out.ps"))

The result is a syntax error. (It works without the <>.)

Thank you! Doesn't seem to work with ABNF though (set `ebnf-syntax` to `abnf`, 
and remove the full stop).

Although it could still be useful, the ebnf2ps package does show its age in 
many respects: non-Unicode, output in EPS rather than PDF or SVG, no 
interactive preview, etc. It's also misplaced (in 'progmodes' despite not being 
a programming mode) and, in effect, abandoned. Does it really belong in Emacs 
core?

(And does anyone use railway diagrams these days?)
