+"""utilities methods and classes for checkers
+
+Base id of standard checkers (used in msg and report ids):
+01: base
+02: classes
+03: format
+04: import
+05: misc
+06: variables
+07: exceptions
+08: similar
+09: design_analysis
+10: newstyle
+11: typecheck
+12: logging
+13: string_format
+14: string_constant
+15: stdlib
+16: python3
+17-50: not yet used: reserved for future internal checkers.
+51-99: perhaps used: reserved for external checkers
+
+The raw_metrics checker has no number associated since it doesn't emit any
+messages nor reports. XXX not true, emit a 07 report !
