// Description:

// e32test\dll\t_xxver2.cpp

// Overview:

// Test matching algorithm for DLL versions. Test aspects of DLL and EXE files.

// API Information:

// RLibrary

// Details:

// - This test makes use of 4 versions of a single DLL, and 15 EXEs which link

// against it.  The EXEs all have different reqirements on which DLL versions

// are acceptable

// - Test that the correct version of linked libraries are used (Run for each

// EXE and for the 16 combinations in which the 4 versions of the DLL can be

// available.  The test is performed with each EXE run in sequence, and again

// with all of them run at the same time)

// - Test that the correct version of dynamically loaded libraries are used and

// the libary exports are as expected.  (Run for each DLL version and for the

// 16 combinations of DLL availability)

// - Test that RLibrary::GetInfo and RLibrary::GetInfoFromHeader return the

// expected data for all DLLs and EXEs

// Platforms/Drives/Compatibility:

// All.

// Assumptions/Requirement/Pre-requisites:

// Failures and causes:

// Base Port information:
