Conda-build

--------------------
* greatly improved ability to create noarch_python packages, 317
* added 'subdir' key to info/index.json
* allow url to be a list or urls, which are tried until one works
* use quotes instead of !!str for versions from the conda skeleton commands
* add conda skeleton cran to generate recipes for packages from CRAN
* add support for adding a readme to a recipe
* add a --quiet option to conda convert

--------------------
* automatically convert absolute symlinks to paths in the build prefix to
relative ones.
* error if there are symlinks to the source directory.
* use the placeholder prefix in text files rather than the build prefix
* allow non-Python packages to be converted to other platforms with conda
convert
* new command conda inspect for inspecting packages. The only subcommand so
far is conda inspect linkages, which shows the dynamic linkages of the
shared object files on Linux.
* correctly handle Unix style has_prefixes on Windows
* run the tests in Binstar build
* only modify egg directories that are part of the package being built
* don't exclude .dylib files from prefix replacement
* ability to build noarch packages
* allow specifying files to always include
* fix for building dependencies in some cases
* print the correct thing for binary files detected with a prefix

-------------------
* set PYTHONNOUSERSITE=1 while running build scripts
* conda index: add error if they try to mix their packages into Anaconda
channel
* fix building recipes with local git urls in Windows
* warn if conda-build is out of date

-------------------
* adapt tests for Windows
* don't use the long build prefix if the short build prefix is already long
* support rewriting library load path for libraries that are in
subdirectories of lib/ on OS X
* allow 'git_rev' as a valid key in 'source', which is identical in behavior
to git_branch and git_tag (all checkout the given revision)
* also grab the full HEAD sha1 and shove it into the environmental
variable GIT_FULL_HASH
* automatically detect text prefix files
* add detect_binary_files_with_prefix flag to meta.yaml to automatically
detect binary files with the prefix and add them to
binary_has_prefix_files
* fix git_info when the author or commit message contains Unicode characters
* allow to pass a url to skeleton pypi
* add NPY_VER environment variable
* fix conda convert --show-imports
* give better error message when encountering a corrupt tarfile in conda
index
* print{ some more helpful information about what is going on at the
beginning of a build
* allow source/path in the meta.yaml to specify a path to the source (which
can be relative to the recipe directory)
* support xz files in Python 3 without requiring unxz
* put spaces after skeleton pypi comments
* correctly detect when to preserve the egg directory and depend on
setuptools in skeleton pypi
* set LIBRARY_PATH and INCLUDE_PATH when building on Unix
* allow selectors to have text after them if they are in a comment
* add CPU_COUNT environment variable to the build

-------------------
* add substantially more tests
* add ability to set additional rpath directories using build/rpaths
* patch command on windows no-longer takes the --binary option
* fix post processing so that name-space packages can be 'flattened' into
a single directory
* don't remove the .svn directory when doing a svn checkout

-------------------
* has_prefix paths must always use /, even on Windows
* fix bug in Windows Python 2
* add .travis.yml
* allow recipes to use requirements.txt
* fix building a package that has Mach-O stub files
* fix recursive package building
* handle empty data size in pypi
* allow an explicitly set empty version string
