In Metrics:  
    host-*.CPUload.{load1,load5,load15}
Function:
    averageSeriesWithWildcards($in, 1)
Out Metrics, Expected:
    host-*.CPUload.load1,
    host-*.CPUload.load5,
    host-*.CPUload.load15
    [exactly 3 series]
Out Metrics, Actual:

whisper-aggregation-backfill

Assumptions:

• All metrics and aggregations have matching retentions
• A proper metric aggregator is already running
• The resulting metric file will then be used in a whisper-fill operation against the aggregator's actual metric files.

Procedure

# I've seen a _lot_ of code written to make bash prompts that are just _OK_,
# but there's no reason to invoke python/ruby/etc and parse git output since
# git ships with a pretty outstanding utility.

# 1. Load the library that already ships with git
source /usr/share/doc/${git_doc_path_here}/contrib/completion/git-prompt.sh

# 2. Set your options
