Comment(by fpietrosanti):
Hi all,
made the following tricks that you can find attached to reduce the size
of TBB/OSX from 32MB to 23MB .
With this tricks it's possible to send TBB/OSX via Gmail using Gettor.
It goes from:
32M /tmp/TorBrowser-2.2.34-3-dev-osx-x86_64-en-US.zip
to
23M /tmp/TorBrowser-7z-wrap2.2.34-3-dev-osx-x86_64-en-US.zip
Probably it would require some better cleanup and integration, that's
just a working poc.

# Now move the file in some other place and just download and run it as
usual
# The first run will compress and delete the internal .7z file
transparently
I tried sending via GMAIL and it works fine.
I am confident that playing another little bit, using this method and
going further, it would be possible to make additional reduction in size.
