[Numpy-discussion] Numpy development version wheels for testing

[Matthew Brett]

Hi,

I've taken advantage of the new travis-ci cron job feature [1] to set
up daily builds of numpy manylinux and OSX wheels for the current
trunk, uploading to:

https://7933911d6844c6c53a7d-47bd50c35cd79bd838daf386af554a83.ssl.cf2.rackcdn.com

The numpy build process already builds Ubuntu Precise numpy wheels for
the current trunk, available at [2], but the cron-job manylinux wheels
have the following advantages:

* they are built the same way as our usual pypi wheels, using
openblas, and so will be closer to the eventual numpy distributed
wheel;
* manylinux wheels will install on all the travis-ci containers, not
just the Precise container;
* manylinux wheels don't need any extra packages installed by apt,
because they are self-contained.

There's an example of use at

Cheers,

Matthew
