 # Regular expression for validating Visual Studio GUIDs.  If the GUID
 # contains lowercase hex letters, MSVS will be fine. However,
 # IncrediBuild BuildConsole will parse the solution file, but then
 # silently skip building the target causing hard to track down errors.
 # Note that this only happens with the BuildConsole, and does not occur
 # if IncrediBuild is executed from inside Visual Studio.  This regex
 # validates that the string looks like a GUID with all uppercase hex
 # letters.
