Strange, it usually gives a noticeable improvement; make sure you compress with "solid mode" ON or whatever is called,
I don't think bzip2 has a "solid mode", at least I couldn't find one in 1.0.2 ?
Here are the file sizes, for your amusement:
42M CB_20061101_rev3164_macx86.tar
18M CB_20061101_rev3164_macx86.tzo
14M CB_20061101_rev3164_macx86.tgz
13M CB_20061101_rev3164_macx86.tbz
14M CB_20061101_rev3164_macx86.zip
8.9M CB_20061101_rev3164_macx86.7z
We could do a .dmg for the final release, it's the same as tgz + the all HFS+ overhead.
I think that's ok with stable releases, but for nightly builds and to save space I think that separating archs is better,
about wx, only if it can be separated from C::B like windows' nightly builds (although it might confuse new users)
"Better" maybe, but it's not the Mac way... :-)
The way that it is going to be is:
Mac OS X -> Universal and Bundled
MacPorts -> split up by arch and lib
Not sure if I mentioned it, but besides wxWidgets the Mac OS X version also bundles a static version of libpng, libjpeg, libtiff, and expat...
the "macppc" builds on BerliOS are all for Panther, by the way.
the "macx86" are all Universal, but BerliOS doesn't have that arch.
