What's the deal with the license? This page mentions only the Eclipse Public License, while the actual Polarsys page and the GitHub repo mention/include three different licenses: the EPL 1.0 (!!!), Eclipse Distribution License 1.0 (BSD-like), and SIL Open Font License 1.1. Should I take that to mean it's multi-licensed and I can use this font under whichever of those licenses I choose? If so, what's the point of making EPL and SIL licensing options when the EDL has far fewer strings attached (and is more obviously compatible with other licenses, notably the GPL)?

Relevantly, the EPL 1.0 is incompatible with any version of the GNU GPL (as is the EPL 2.0 by default).
