Subject: [ANN] flay 2.2.0 Released

flay version 2.2.0 has been released!

* repo: <https://github.com/seattlerb/flay>
* rdoc: <http://seattlerb.rubyforge.org/flay>
* home: <http://ruby.sadi.st/>

Flay analyzes code for structural similarities. Differences in literal
values, variable, class, method names, whitespace, programming style,
braces vs do/end, etc are all ignored. Making this totally rad.

Changes:

### 2.2.0 / 2013-04-09

Semantic versioning doesn't take into account how AWESOME a release
is. In this case, it severely falls short. I'd jump to 4.0 if I could.

* 2 major enhancements:

  * Added --fuzzy (ie copy, paste, & modify) duplication detection.
  * Added --liberal, which changes the way prune works to identify more duplication.

* 12 minor enhancements:

  * Added -# to turn off item numbering. Helps with diffs to compare runs over time.
  * Added Sexp#+.
  * Added Sexp#code_index to specify where *code starts in some sexps.
  * Added Sexp#has_code?.
  * Added Sexp#initalize_copy to propagate file/line/modified info.
  * Added Sexp#modified, #modified=, and #modified?.
  * Added Sexp#split_at(n). (Something I've wanted in Array for ages).
  * Added Sexp#split_code.
  * Added mass and diff options to rake debug.
  * Added rake run task w/ mass, diff, and liberal options
  * Made report's sort more stable, so I can do better comparison runs.
  * Wrapped Sexp#[] to propagate file/line/modified info.
