As of version 1.4.0 and later, the TortoiseSVN installer doesn't provide
the user with the option to set the SVN_ASP_DOT_NET_HACK
environment variable
anymore, since that caused many problems and confusion for users who
always install everything no matter whether they know
what it is for.
But the feature is still available in TortoiseSVN and other svn clients.
To enable it you have to set the Windows environment variable named
ASPDOTNETHACK to 1. Actually, the value
of that environment variable doesn't matter: if the variable exists
the feature is active.
Please note that this hack is only necessary if you're still using VS.NET2002. All later versions of Visual Studio do not require this hack to be activated! So unless you're using that ancient tool, DO NOT USE THIS!
