is there any better method to externalize some configure info from code?

i wanna get some var or constant out of the code files.
pls show your ways.thanks!

Check the Configuration Files Loader (http://
revolutiononrails.blogspot.com/2007/03/plugin-release-configuration-
files.html) gem/plugin. It allows to put whatever you need into a YAML
file under the config/ directory of an application/plugin/gem and then
load it sectioned/parsed/ERBd.
