-========================== WIP
+The members tt(name) and tt(message) have trivial implementations.  The member
+tt(equivalent) receives an tt(error_code) object and an error condition enum
+value (as an tt(int)). The function must return tt(true) if the provided
+tt(error_code) is associated with the provided error condition enum
+value. tt(Equivalent) itself doesn't perform those checks. Rather, it

+tt(equivalent) function to perform the test:
+        verbinsert(-s4 //impl
+            examples/errcode/conditioncategory/equivalent.cc)
 
+Next we look at the class tt(ErrorCondition). It contains a
+tt(ConditionCategory) object (i.e., em(the) tt(ConditionCategory) object), and
+a tt(unsorted_map), mapping condition names to their indices in the
+tt(ConditionCategory's) vector. Other than that it's a rather plain class,
+offering members to retrieve the enum values of the various error conditions,
+and returning conditions' names given their numbers. Error condition enum
+values are simply defined as their indices in the tt(ConditionCategory's)
+vector, statically cast to the enum tt(ErrorCondition::Enum).
 
+tt(Enum) by itself is defined as mere enumeration name, promoted to an
+tt(ErrorConditionEnum) by the tt(std::is_error_condition_enum) trait class
+specialization (comparable to what the tt(is_error_code_enum) trait class
+accomplished for our enums like tt(CalculatorError)). Here is the

+Error conditions objects themselves are returned by a function
+tt(make_error_condition), expecting an tt(ErrorConditionEnum) value as its
+argument, and internally using an tt(std::error_category) that is associated
+with the various error condition enum values, much like tt(CalculatorCategory)
+was associated with the tt(CalculatorError) enumeration. Since
+tt(ConditionCategory) is a singleton, it can directly pass that singleton

-: their uniqueness can be guaranteed by another class,
-tt(ErrorCondition), which is also a singleton. That class defines an empty
-tt(enum Enum), which is promoted to an tt(ErrorConditionEnum) by the
-tt(std::is_error_condition_enum) trait class specialization:
