On my system, the 8 largest packages are:
qt-devel pulls in more than a whole Win32 environment!
Looking at where that all comes from, it's mostly from documentation:
[david@desktop ~]$ du -hsc /usr/share/doc/qt-devel-3.3.5/*
Most people only want qt-devel in order to compile Qt + KDE applications. The
documentation is just a wasted download for us. (The qt-devel RPM is 15Mb - it
takes several minutes even on broadband - I have 512kbps).
An extra qt-devel-apidocs sub-package ought to be created with this stuff, as
it was for kdelibs-devel.
Thank you for your consideration!
it's now fixed in rawhide. Thanks for your report.
