-Pylint is a Python static code analysis tool which looks for programming errors,
-helps enforcing a coding standard, sniffs for code smells and offers simple refactoring suggestions.
-It's highly configurable, having special pragmas to control its errors and warnings from within
-your code, as well as from an extensive configuration file. It is also possible to write your own
-plugins for adding your own checks or for extending pylint in one way or another.
+Pylint is a Python source code analyzer which looks for programming
+errors, helps enforcing a coding standard and sniffs for some code
+smells (as defined in Martin Fowler's Refactoring book).
+Pylint can be seen as another PyChecker since nearly all tests you
+can do with PyChecker can also be done with Pylint. However, Pylint
+offers some more features, like checking length of lines of code,
+checking if variable names are well-formed according to your coding
+standard, or checking if declared interfaces are truly implemented,
+and much more.
+Additionally, it is possible to write plugins to add your own checks.
