Constant Summary

SLUG_REGEX =

Tests whether a string is a valid Cadmus slug or not. A valid Cadmus slug consists of one or more valid slug parts separated by forward slashes. A valid slug part consists of a lower-case letter followed by any combination of lower-case letters, digits, and hyphens.

For example, +about-us/people+, +special-deals+, and +winter-2012+ are all valid slugs, but +3-things+, +123+, +nobody-lives-here!+, and +/root-page+ aren't.
