// Revision History
|
||||
// 29 May 01 Added operator classes for << and >>. Added input and output
|
||||
// iterator helper classes. Added classes to connect equality and
|
||||
// relational operators. Added classes for groups of related
|
||||
// operators. Reimplemented example operator and iterator helper
|
||||
// classes in terms of the new groups. (Daryle Walker, with help
|
||||
// from Alexy Gurtovoy)
|
||||
// 11 Feb 01 Fixed bugs in the iterator helpers which prevented explicitly
|
||||
// supplied arguments from actually being used (Dave Abrahams)
|
||||
// 04 Jul 00 Fixed NO_OPERATORS_IN_NAMESPACE bugs, major cleanup and
