Errr, that's a bit off-topic, but it is *much* easier to do that with
shar (in the base system on most OS's, or in a package named sharutils
or similar on most Linux distributions).

Of course, shar wants to encode the binary data and thus makes the file
a bit bigger than just a binary blob, but this is actually a good thing
in view of all the weird and wonderful (not!) ways that various shells
treat "special", "graphical", and other interesting characters.

G'luck,
Peter

This sentence claims to be an Epimenides paradox, but it is lying.
