Large svn external

I have a project which uses a large library residing in its own repository.

Using: TortoiseSVN, the server is running an enterprise edition of VisualSVN

The project itself has the "standard" structure:

• trunk
• tags
• branches

In each branch, tag, and trunk is the librar开发者_JS百科y, set as an external (svn:external property). If I get the entire tree, I get the library several times, which is just getting too ridiculously repetitive.

Is there a recommended structure for this? Or perhaps a way not to get all externals (because other externals are much smaller, easier to manipulate)?

The TortoiseSVN help has an appendix on including a common subproject. If the library isn't likely to change, I think using a relative location (the third option listed) is probably the best.
