This adds tests for setupEnv, and also updates some documentation to
mirror the current state of plugins.

This adds a hidden 'helm doc' command that generates documentation out
of the Helm help text.

Currently it can create:

- man pages for HELM(1)
- Markdown documentation
- bash autocompletions

Those are the three built-ins for Cobra.

The command is hidden so that it doesn't show up to the regular user,
since this is really a specialized task. It has the advantage of making
it trivially easy to install man pages and bash completion at installation time.

This adds a backend for a plugin system.

Closes #1572

This replaces the old set parser with a brand new one. This also changes
the internal algorithm from duplicating YAML to merging YAML, which
might solve a problem one user reported in chat, but which was never
captured in an issue.

Closes #1540
Closes #1556

This adds support for packs, pre-configured chart patterns that can be
used to quickly create a custom layout for your new chart.

This raises the limit from 14 to 53 chars based on the Kubernetes 1.4
name limit.

Closes #1528

This documents YAML and provides information about how Helm and
Kubernetes interpret the YAML.

Downloading of charts and helm itself happened over http. This
change moves to use https as that is available with valid certs.

A bucket name in the path can be migrated to a custom k8s domain
name. This is in preperation for that.

Consistently add spacing for '{{ $foo }}'

This adds a detailed document on writing templates in Helm. This is NOT
a best-practices guide, but a thorough introduction to templates in
Helm.

The solution to #1455 is to configure dnsmasq on each of your nodes.
This adds brief documentation on how to do so.

Closes #1455

This adds a couple of examples for building an application chart for
complex multi-part applications.

This adds a place to put distribution-specific information about
different distributions of Kubernetes.

This pass through fixed formatting, examples, and technical information
to reflect the current state of Helm. Also added some pointers for
using a regular webserver.

This adds documentation for 'scripts/get'.

This prompts the user to enter a passphrase if the given PGP key is
encrypted.

Closes #1447

This provides an example of an in-place upgrade to Tiller using `kubectl
set image`.

Fixes #1393

This refreshes docs, as discussed in #719, and adds a few new sections
to the docs.

Closes #719
