Brownie wants to solve these problems by providing all these small things well documented, well tested and most importantly right now when you need it.
Take a look at the documentation for further information, visit Github for development or issue tracking or fetch the latest development version.
Brownie runs on Python 2.5-2.7 (tested on CPython and PyPy). In order to install it simply run pip install brownie or easy_install brownie, should you prefer the latter, to get the latest stable version.
If you really need to, you can also install the development version of Brownie with pip install brownie==dev. However I do not recommend it.
Should you want to participate in the development, fork the repository on Github and take a moment to read Contributing, for a couple of general and not so general guidelines you should follow.
