      • -
    • Eventually, the occurrences of the character "-" will be -replaced by "_" in all λδ-related identifiers.
      • -
    • In particular, this refactoring involves file names and -path names.
      • -
    • The permanent λδ URL is sheduled to become http://lambda_delta.info on -December 2012.
