+/*Package repo implements the Helm Chart Repository.
+
+A chart repository is an HTTP server that provides information on charts. A local
+repository cache is an on-disk representation of a chart repository.
+
+There are two important file formats for chart repositories.
+
+The first is the 'index.yaml' format, which is expressed like this:
+
+	apiVersion: v1
+	entries:
+	  frobnitz:
+	  - created: 2016-09-29T12:14:34.830161306-06:00
+		description: This is a frobnitz.
+		digest: 587bd19a9bd9d2bc4a6d25ab91c8c8e7042c47b4ac246e37bf8e1e74386190f4
+		home: http://example.com
+		keywords:
+		- frobnitz
+		- sprocket
+		- dodad
+		maintainers:
+		- email: helm@example.com
+		  name: The Helm Team
+		- email: nobody@example.com
+		  name: Someone Else
+		name: frobnitz
+		urls:
+		- http://example-charts.com/testdata/repository/frobnitz-1.2.3.tgz
+		version: 1.2.3
+	  sprocket:
+	  - created: 2016-09-29T12:14:34.830507606-06:00
+		description: This is a sprocket"
+		digest: 8505ff813c39502cc849a38e1e4a8ac24b8e6e1dcea88f4c34ad9b7439685ae6
+		home: http://example.com
+		keywords:
+		- frobnitz
+		- sprocket
+		- dodad
+		maintainers:
+		- email: helm@example.com
+		  name: The Helm Team
+		- email: nobody@example.com
+		  name: Someone Else
+		name: sprocket
+		urls:
+		- http://example-charts.com/testdata/repository/sprocket-1.2.0.tgz
+		version: 1.2.0
+	generated: 2016-09-29T12:14:34.829721375-06:00
+
+An index.yaml file contains the necessary descriptive information about what
+charts are available in a repository, and how to get them.
+
+The second file format is the repositories.yaml file format. This file is for
+facilitating local cached copies of one or more chart repositories.
+
+The format of a repository.yaml file is:
+
+	apiVersion: v1
+	generated: TIMESTAMP
+	repositories:
+	  - name: stable
+	    url: http://example.com/charts
+		cache: stable-index.yaml
+	  - name: incubator
+	    url: http://example.com/incubator
+		cache: incubator-index.yaml
+
+This file maps three bits of information about a repository:
+
+	- The name the user uses to refer to it
+	- The fully qualified URL to the repository (index.yaml will be appended)
+    - The name of the local cachefile
+
+The format for both files was changed after Helm v2.0.0-Alpha.4. Helm is not
+backwards compatible with those earlier versions.
