Detailed Description

template<class StrmBuf>
class rpa::streambuf_proxy_base< StrmBuf >

This is a proxy for using a pointer to a streambuf just like a streambuf. This must have a default constructor. Could not find any other way to expose protected methods. This could be avoided if stream buffers had only public virtual methods.
