Hi,

This is the code for my Markdown.sublime-build, which I included under Sublime Text 2\Packages\User

{ "cmd": "multimarkdown.exe", "-b", "$file"], "selector": "source.md", "source.mmd", "source.markdown"], "shell": true }

The problem is that when I open a new file with md mmd or markdown extension the building system is not automatically selected. Any idea what is wrong?
