A .dmg file is an image of an HFS+ format disk.  These are commonly
used under OS X for installing apps, similar to mounting a .iso file with the
loop device on linux.  The default allows users to run programs --
See: <http://aroundcny.com/technofile/texts/mac042705.html>

<http://hem.bredband.net/catacombae/hfsx.html> is a java app
to read files from HFS+ on Win32.  In principle, linux can do:

# modprobe hfsplus
# mount -t hfsplus file.dmg /mnt/disk -o loop,ro

(but it didn't work for me on debian testing -- dmesg says:
hfs: unable to find HFS+ superblock

These days it is helpful to mention whether the .dmg files include support
for Intel machines.
