    This interface is a web based user interface that provides less
    features but a better user experience than the old web based
    interface of RefactorErl. Its main features are the following.
        * Running and exploring semantic queries.
        * Query construct assistant (auto-complete)
        * Persistent queries
        * Management of (possibly multiple) running queries
        * Database operations
        * Ability to mark files with error forms
        * Dependency examinations

- Wx

    This interface is a standard desktop application requiring no extra
    dependency. Its main features are the following.
        * Database management
        * Semantic queries and skeletons
        * Dependency graphs
        * Duplicated code analysis
        * Code investigations.

- Clone IdentifiErl

    Clone IdentifiErl is a prototype duplicated code detector software,
    which provides two separate ways to identify code clones.
        * The algorithm, called matrix, is an AST/metric based
        detector with which clones containing at least one expression
        can be found.
        * The algorithm, called sw_metrics, is a software metrics based
        detector with which similar function pairs can be identified.
    It is available via the ri module: ri:clone_identifierl/0,
    ri:clone_identifierl/1.

- Semantic query (sq)
    - 'in' operator, which can be used in filters, is introduced.
      To illustrate its usage, consider the following 2 semantic queries,
      which are semantically equivalent with each other.
        * mods.funs[name = a or name = b or name = c]
        * mods.funs[name in |a,b,c|]

    - Position based @expr selector is expanded (now works with macros).

    - The evaluation of semantic queries is speeded up: selectors and
      properties are calculated in parallel.

    - Querying macro_value of such macros which are expanded not to
      expressions is supported.

technical fixes
------------------------------------------------------------------------
- The evaluation of such semantic queries that containing a regexp filter(~)
  whose operand is a quoted atom (e.g.: ri:q("mods.funs[name ~ 'f']"))
  was fixed.

- Exceptional nodes handling of the dependency analyser was fixed.

- A bug that caused errors while a file containing include forms is being
  incrementally updated was eliminated.
