Perl 5 / official or unofficial logo

[kytrinyx]

As described in #24, this weekend we're designing proper icons for each of the language tracks on Exercism.

In order to help speed us through this work, it would be helpful to know whether or not the language has a logo, whether official or unofficial, what that logo is, and what the usage rights of it are.

If you know things, awesome! Drop that knowledge below. If you don't but want to help do research, we will be very grateful.

Here's a template for you to fill out:

### Official Logo

### Unofficial Logo

### Link to Logo

### License, Usage Rights

For each heading, please list what you know or find out. If something is irrelevant due to something listed in an earlier heading, say n/a (not applicable).

We did some research a while back, and might have some useful information at the bottom of the README.md. (Look for "Perl 5 icon")

You can see whatever icon we've put together for the track in the img directory of the track. Sometimes this is based on something official, sometimes it's just desperation made tangible. (You'll see why we're working with real designers.)

Official Logo

The Perl Foundation's official logo is an Onion.

Unofficial Logo

Due to the cover of O'Reilly's Programming Perl, a Camel is often associated with Perl 5.

Perl 5 also has an unofficial logo of a raptor due to keynote speech given by MST.
