Do nothing. All files in this dir are eager loaded in production and lazy loaded in development by default.

Things to Look for When Evaluating Encoders

"Our encoder mixes DCT synergies and gamma radiation to provide excellent quality that abides by industry standard salsa dancing techniques, using adaptive streaming techniques." — Beamr, probably.

First Steps

First, verify they actually have a product to sell that actually exists and can be tested in-house.

Warning signs: incredibly vague descriptions of the product, lots of "patent pending" claims with no real patents to be found, and insistence that they can do the testing for you and provide metrics instead of letting you test it yourself.

	Symptoms may include:

	1. Knowing that you will have to write a router for the 10th time just because someone said YAGNI
	(and knowing that having said "router" you would likely want it _both_ ways, yes I mean it thank you)
	2. When talking about yourself as a developer you say
	things like "I escape my URLs and preferably auto, and yes this includes the router"
	3. You know you just don't need to rememder to have a form tag without do..end. because you use markaby anyway.
	And you want your URL escaped
	4. It doesn't feel right unless you have snatched escape_and_sanitize_ugly_html_gunk from bigframework and
	of course you find out that it requires bigframework-*.gem, and the backing class for escape_and_sanitize
