Detailed Description

template<class TOutput, char FalseCharacter>
class ASCIIBoolFieldHandler< TOutput, FalseCharacter >

A special handler for bool fields in the GT/GMT DBs. These can't be imported in the generic way because bool values are returned as char '0' for false and '1' for true from the database. Basically, all values that are != FalseCharacter are treated as true (in adherence to the venerable C tradition).
