  27 # 1) Add a module offset code.  Add yours to the bottom of the list
  28 # right below this comment, adding 1.
  29 #
  30 # 2) In your module, define a header file which uses one of the
  31 # NE_ERROR_GENERATExxxxxx macros.  Some examples below:
  32 #
  33 #    #define NS_ERROR_MYMODULE_MYERROR1 \
