You can download the rules from:

------------------

Gofer new

  squeaksource: 'FindBugs';

  package: 'MiningLintRules-PharoMigration'; "1.4 -> 2.0"

  package: 'MiningLintRules-PharoMigrationNew'; "some more rules 1.4 -> 2.0"

  package: 'MiningLintRules-Pharo13'; "1.3 -> 1.4"

  load.

------------------

You can run such rules by selecting the groups *Mined rules* in the the Critcs Browser.

Note that this not the solution for all the problems, just a help :)

The next plan is to create rules on demand (instead of providing predefined rules like the ones above).

So, you ask how should I update "this", and then we give you a rule changing "this" for "that".
