/* blorblow.h: Low-level header file for Blorb library, version 1.0.2.
|
|
Designed by Andrew Plotkin <erkyrath@eblong.com>

http://www.eblong.com/zarf/blorb/index.html
|
|
|
|
This header is generally of interest only to the Blorb library code
|
|
itself (blorblib.c); it defines things internal to the library.
|
|
An interpreter shouldn't have to include this file. The only time you
|
|
might need to include this is if you're writing a Blorb file analysis
|
|
tool (such as blorbscan), or a transformation tool, or some such thing.
