+/*Package chartutil contains tools for working with charts.
+
+Charts are described in the chart package (pkg/chart).
+This package provides utilities for serializing and deserializing charts.
+
+A chart can be represented on the file system in one of two ways:
+
+	- As a directory that contains a Chart.yaml file and other chart things.
+	- As a tarred gzipped file containing a directory that then contains a
+	Chart.yaml file.
+
+This package provides utilities for working with those file formats.
+
+The preferred way of loading a chart is using 'loader.Load`:
+
+	chart, err := loader.Load(filename)
+
+This will attempt to discover whether the file at 'filename' is a directory or
+a chart archive. It will then load accordingly.
+
+For accepting raw compressed tar file data from an io.Reader, the
+'loader.LoadArchive()' will read in the data, uncompress it, and unpack it
+into a Chart.
+
+When creating charts in memory, use the 'helm.sh/helm/pkg/chart'
+package directly.
