+ * A simple utility for shortening identifiers in a stable way. Generates
+ * short substitution strings deterministically, using a compact
+ * (1 to 6 characters in length) repesentation of a 32-bit hash of the key.
+ * The string is suitable to be used as a JavaScript or CSS identifier.
+ * Collisions are possible but unlikely, depending on the underlying hash algorithm used.
+ *
+ * This substitution scheme uses case-sensitive names for maximum
+ * compression. Digits are also allowed in all but the first character of a
+ * class name. There are a few characters allowed by the CSS grammar that we
+ * choose not to use (e.g. the underscore and hyphen), to keep names simple.
+ *
+ * Xid should maintain as minimal dependencies as possible to ease its
+ * integration with other tools, such as server side HTML generators.
