On branch-trunk-win, some work was committed to convert custom build scripting to Python as a cross-platform solution to support builds on both Linux and Windows. The community has since rejected this solution. This issue tracks removal of the Python build code from branch-trunk-win.
This will restore branch-trunk-win to the same state as trunk, which uses shell for custom build scripting. This means that developers working on branch-trunk-win will once again need sh.exe on the PATH to build the distribution. This will be a temporary state. A subsequent jira will add build scripts specific to Windows, using a language more common in a Windows development environment. The community has approved minimal use of multiple platform-specific scripting languages.
