In the developer guide section 3.3.4
(http://www.wireshark.org/docs/wsdg_html_chunked/ChSrcObtain.html) you can
read:
The officially released source files can be found at:
http://www.wireshark.org/download/. You should use these sources if you want
to build Wireshark on your platform for productive use.
Why don't I get the same files, when I checkout the SVN repository?
svn export http://anonsvn.wireshark.org/wireshark/releases/wireshark-1.6.0
wireshark
compared to
http://www.wireshark.org/download/src/wireshark-1.6.0.tar.bz2
