## Overview

Manages the release of a python library.

* auto generates a changelog entry (using github's compare view and commit urls)
* cli that follows [semantic versioning][0] principles to auto-increment the library version
* runs the library tests
* test package installation from a tarball and pypi
* uploads to pypi
* tags the github repo

## Usage

An application wanting to use `changes` must meet these requirements:

* on [github](https://github.com)
* `setup.py`
* `CHANGELOG.md`
* `<app_name>/__init__.py` with `__version__` and `__url__`
* supports executing tests with [`nosetests`][2] or [`tox`][3]

Install `changes`:

pip install changes

Run the cli:

```
changes.

Usage:
changes [options] <app_name> changelog
changes [options] <app_name> release
changes [options] <app_name> version
changes [options] <app_name> test
changes [options] <app_name> install
changes [options] <app_name> upload
changes [options] <app_name> pypi
changes [options] <app_name> tag

changes -h | --help

Options:
--new-version=<ver> Specify version.
-p --patch Patch-level version increment.
-m --minor Minor-level version increment.
-M --major Minor-level version increment.

-h --help Show this screen.

--pypi=<pypi> Use alternative package index
--dry-run Prints the commands that would have been executed.
--skip-changelog For the release task: should the changelog be generated
and committed?
--tox Use tox instead of nosetests
--test-command=<cmd> Command to use to test the newly installed package
--debug Debug output.

The commands do the following:
changelog Generates an automatic changelog from your commit messages
version Increments the __version__ attribute of your module's __init__
test Runs your tests with nosetests
install Attempts to install the sdist
tag Tags your git repo with the new version number
upload Uploads your project with setup.py clean sdist upload
pypi Attempts to install your package from pypi
release Runs all the previous commands
```

The default workflow is to run the `changelog` command to autogenerate
a changelog entry based on your commit messages.

You're probably going to want to edit that a bit, so `changes` won't commit it,
unless you're running the `release` command.

The remaining tasks can be automated with the `release` command (the
`--skip-changelog` option prevents `release` from regenerating the automatic changelog)
