@ in filename using Maxscript

Using Maxsctipt: Exporting a file the following code works fine:

caption:"Caption" \
types:"text(*.txt)|*.txt|All|*.*|" \
filename:(sysinfo.currentdir + @"\some_text.txt")

I am wondering what the significance the @ symbol has?

    Bottomline you don't need to escape characters in the string if there are any "illegal" characters in it, especially helpful when dealing with paths loads of \ 's
