+ -- CODEFIX Facility --
+ -----------------------
+
+ -- The GPS and GNATBench IDE's have a codefix facility that allows for
+ -- automatic correction of a subset of the errors and warnings issued
+ -- by the compiler. This is done by recognizing the text of specific
+ -- messages using appropriate matching patterns.
+
+ -- The text of such messages should not be altered without coordinating
+ -- with the codefix code. All such messages are marked by a specific
+ -- style of comments, as shown by the following example:
+
+ -- Error_Msg_N -- CODEFIX
+ -- (parameters ....)
+
+ -- Any message marked with this -- CODEFIX comment should not be modified
+ -- without appropriate coordination. If new messages are added which may
+ -- be susceptible to automatic codefix action, they are marked using:
+
+ -- Error_Msg -- CODEFIX???
+ -- (parameters)
+
+ -- And subsequently either the appropriate code is added to codefix and the
+ -- ??? are removed, or it is determined that this is not an appropriate
+ -- case for codefix action, and the comment is removed.
