banterpixra is a tool to generate syntax diagrams from BNF-esque
grammars. It's written in Chicken Scheme, and outputs the diagrams
in SVG.

As it is distributed as a Chicken egg, just type `chicken-install`
within the source directory to install it, or (without a source directory)
type `chicken-install banterpixra` to install the latest stable release.

The grammar language is simple, as is the command-line syntax.

See
[the banterpixra grammar](http://www.kitten-technologies.co.uk/projects/banterpixra/banterpixra.ruleset)
for a sample of the grammar (that also happens to document the grammar
format itself, and the banterpixra command-line arguments).

The resulting diagram is:

The name "banterpixra" is [Lojban](http://www.lojban.org/) for "language artist", and is
pronounce something like "ban-tare-pihra". The name was chosen
due to my intention to use banterpixra to produce syntax diagrams
for the Lojban langauge. By Lojban contention, banterpixra should never be written with a capital first letter.
