Microsoft toolkit out under open-source licence
===================================
Microsoft has released its Windows Template Library (WTL) technology under an open-source licence, marking the second time the company has turned one of its projects over to the SourceForge.net development site.
WTL is a toolkit for developing lightweight Windows applications. It has always been a little-publicised and barely documented alternative to the Microsoft Foundation Classes (MFC) toolkit."
Ladd said he prefers WTL as a smaller, faster alternative to MFC.
"MFC is a big, bloated library that's not well designed. WTL was developed internally for people at Microsoft. It's small and fast. If you're going to write pure C++ code, I recommend people go with WTL."
WiX and WTL both were released under the Common Public Licence (CPL), a license developed by IBM that does not require derivative works to be freely released, as the GPL does.
