There are some SVN repositories out there which don't have revision information
tied to externals. By using ignoreExternals, fetchsvn won't fetch these
externals anymore, so the fetch won't fail with a checksum mismatch, should
there be some changes in some of those external repositories.

An aggregate is a trivial build that depends on other builds. This is
intended to provide a declarative replacement of Hydra's "view"
mechanism.
For instance, you can define an aggregate named "critical" that
depends on a selected set of jobs:
critical = releaseTools.aggregate
{ name = "foo-${tarball.version}";
members =
[ tarball
build.x86_64-linux
...
];
meta.description = "Release-critical builds";
};
The "critical" build will only succeed if all its members
(dependencies) succeed.

Commit 1764ea2b0a introduced changes to libxslt
in an awkward way to avoid re-builds on Linux. This patch has been simplified
during this merge.
uses for its core libraries, so that these files integrate seamlessly into one
profile, living right next to each other. This change is eventually going to
simply our with-packages wrapper quite a bit.
This branch refactors xfce and updates it to 4.10. I had been hoping to
find someone besides Vlada to test this (I don't use xfce), but no one
has come forward yet in 2 weeks so if this breaks something they can
make an issue or fix it. It all looks good by inspection.
According to <http://hackage.haskell.org/trac/ghc/ticket/4013>, this
feature won't work with XCode versions older than 3.2.
This means that Mac users will have considerably larger binaries because
some build-time dependencies (such as HTTP) will be mis-detected as
run-time dependencies.
In the master branch, doCheck defaults to 'false', which means that no package
will change its hash unless its doCheck field is set to 'true' explicitly. In
the stdenv-updates branch, however, all Haskell packages have a default setting
of 'doCheck=true'. Once that branch has been merged, filtering doCheck is no
longer necessary.

Merge conflicts seemed trivial, but a look from viric and aszlig would be nice.
This patch configures all Cabal builds with '--enable-split-objs' unless the
Nix expression explicitly sets "enableSplitObjs = false". The Cabal manual [1]
describes this option as follows:
| The GHC -split-objs reduces the final size of the executables that use the
| library by allowing them to link with only the bits that they use rather
| than the entire library. The downside is that building the library takes
| longer and uses considerably more memory.
One immediate benefit of this change is that the 'darcs' closure defined in the
top-level no longer refers to GHC. The same is probably true with other
executable packages.

The use case is to do a deep replacement of a dependency without rebuilding the entire tree.
For example, suppose a security hole is found in glibc and a patch released. Ideally, you'd
just rebuild everything, but that takes time, space, and CPU that you might not have, so in
the mean time you could build a safe version of, say, firefox with:
firefox-safe = replace-dependency { drv = firefox; old-dependency = glibc; new-dependency = patched-glibc; };
Building firefox-safe will rebuild glibc, but only do a simple copy/string replacement on all other dependencies
of firefox. On my system (MBP 13" mid-2012), after a new glibc had been build building firefox took around 11 seconds.
See the comments in the file for more details.
