Where the drawings come from

The 2525E and 2525D drawings are the Defense Information Systems Agency's SVG building blocks, as published under the Apache-2.0 licence, imported and then corrected against the standard's own plates where they differ. The 2525C and 2525B drawings come from Apache-2.0 2525C and 2525B fonts. The APP-6(B) drawings that differ from 2525B's are traced from APP-6(B)'s plates. THIRD-PARTY-NOTICES in each package names the sources and carries their licence.
