+ ** Note 1: If your error or warning message does not contain source line
+ location use syntax `// Line : 0'
+
+ ** Note 2: Because in some special cases the error message can differ
+ between runtimes. The special syntax exists where you can specify message
+ for 2.0 runtime.
+
+ For example:
+
+ // CS0057: Uknown error
+ // GMCS0057: Uknown error 2.0
+ // Line: 10
