Cheyenne's configuration file (httpd.cfg) uses REBOL as data storage format. This choice provides a simple format to read/write both for humans and for Cheyenne's config file parser. The file is structured using REBOL blocks in, at least, 3 main sections.
Typical httpd.cfg file structure :
modules [...] globals [...] default [...]
Minimal configuration file :
modules [static] globals [] default [root-dir %www/]
This minimal file would make Cheyenne serves only static content from Cheyenne's www/ local folder.
