+/**
+ * ZendCodeAnalyzerTask analyze PHP source code using the ZendCodeAnalyzer included in Zend Studio 5.1
+ * 
+ * Available warnings:
+ * 
+ * zend-error                 var: Deprecated. Please use the public/private/protected modifiers
+ * var-arg-unused             Function argument 'parser' is never used.
+ * var-once                   Variable 'comment' encountered only once. May be a typo?
+ * var-value-unused           Value assigned to variable 'args' is never used
+ * return-empty-val           Function 'set_object' has both empty return and return with value.
+ * if-if-else                 In if-if-else construction else relates to the closest if. Use braces to make the code clearer.
+ * bool-assign                Assignment seen where boolean expression is expected. Did you mean '==' instead of '='?
+ * var-use-before-def         Variable 'matches' is used before it was assigned.
+ * empty-cond                 Condition without a body
+ * var-ref-notmodified        Function parameter 'parser' is passed by reference but never modified. Consider passing by value.
+ * include-var                include/require with user-accessible variable can be dangerous. Consider using constant instead.
+ * expr-unused                Expression result is never used
+ * bad-escape                 Bad escape sequence: \/, did you mean \\/?
+ * var-use-before-def-global  Global variable 'argv' is used without being assigned. You are probably relying on register_globals feature of PHP. Note that this feature is off by default.
+ * call-time-ref              Call-time reference is deprecated. Define function as accepting parameter by reference instead.
+ * return-noref               Function 'loadlintschema' returns reference but the value is not assigned by reference. Maybe you meant '=&' instead of '='?
+ * unreach-code               Unreachable code in function 'loginUser'.
+ * var-global-unused          Global variable 'fixErrors' is defined but never used.
+ * break-depth                Break/continue with depth more than current nesting level. 
+ *
