In many cases, people format a user-readable content within
Splunk -- either because they need to send an e-mail, show
a text in a dashboard, or push the results to JIRA or other
ticketing tool.
But when they format the actual readable message, they have
to use a a very simple formatting techniques, making the
query look rather ugly and difficult to maintain.
With a template, it's possible to specify the resulting
text with placeholders, which will later on be properly
populated by the query results. And that's exactly
what jinja2format does.
