Any individual, organization, or company may use the "Powered by Perl" or "Programming Republic of Perl" logos... The Perl logo, the Perl Foundation logo, and the bare onion logo are available for use by Perl Mongers, Perl Monks, and Perl.org, which are part of TPF.
.... This authorization to use the Perl logo is limited to uses by the organizations themselves, and doesn't extend to individual members. Representatives of the organizations should contact us at email@example.com to obtain high-resolution versions of the Perl logo. ["Perl trademark"]
Two poky little PNGs of the slogan-tainted logos that you are allowed to use are proffered on the page. Contrast that with this:
Projects and companies that use Python are encouraged to incorporate the Python logo on their websites, brochures, packaging, and elsewhere to indicate suitability for use with Python or implementation in Python. ["The Python Logo"]
They give you everything from generic PNGs to two flavors of SVG and even Photoshop format. The extremely reasonable detailed trademark usage guidelines even give you permission to make derived logos.
Perl: there's more than one way to do it. Except if you're talking about using the logo.
