The .reg file format isn't very well specified. These 2 links have some
pointers:

http://support.microsoft.com/kb/310516
http://en.wikipedia.org/wiki/Windows_Registry#.REG_files

Both mention that a .reg file is validated by the contents of the first line,
which must be this magic string. So any comments should come after, to make sure
every windows version will happily consume the file.
