;;; Commentary:
|
|
|
|
;;; Org-Babel support for using ebnf2ps to generate encapsulated postscript
|
|
;;; railroad diagrams. It recogises these arguments:
|
|
;;;
|
|
;;; :file is required; it must include the extension '.eps.' All the rules
|
|
;;; in the block will be drawn in the same file. This is done by
|
|
;;; inserting a '[<file>' comment at the start of the block (see the
|
|
;;; documentation for ebnf-eps-buffer for more information).
|
|
;;;
|
|
;;; :style specifies a value in ebnf-style-database. This provides the
|
|
;;; ability to customise the output. The style can also specify the
|
|
;;; grammar syntax (by setting ebnf-syntax); note that only ebnf,
|
|
;;; iso-ebnf, and yacc are supported by this file.
