+Copyright and licensing information
+======================================
+
+This is a collection of vectorized symbols for use on the APRS system.
+
+The copyright status of this collection is a bit complicated, since the
+symbols come from various sources, each having different copyright owners.
+
+Most of the vectorized symbols are loosely based on the low-resolution
+"standard" bitmap symbol set as distributed by Stephen Smith, WA8LMF.  That
+set is used by most APRS software around the world.  The low resolution of
+those symbols does not allow direct vector conversion, so I've drawn new
+symbols in a similar layout.  The vector versions try to mimic the original
+appearance and colours, with the intention of keeping the set recognizable
+and familiar to existing users.  In some cases the vector versions are
+probably similar enough to the originals, so that they cannot be considered
+"original work" by myself.  In some of these cases, the originals are
+probably also mimicking someone else's design.
+
+The original symbols do not come with any information on their licensing.
+They've been distributed with a lot of APRS software over time, but I don't
+know who designed which symbol originally. Most likely all of them are
+drawn by one of:
+
+  * Roger Barker, G4IDE, "original set provided with UI-View" (SK)
+  * Steve Dimse, KH4G, "U.S. customary set"
+  * Stephen Smith, WA8LMF
+
+The Adobe Illustrator (.ai) file contains a copy of the original bitmaps
+as a hidden layer, just for reference.
+
+Some symbols I obtained from other sources, such as Wikipedia. In those
+cases I picked SVG versions which allow commercial reuse (source known, and
+the work is placed on public domain, or with a CC license which allows
+adaptation and commercial reuse).
+
+Some symbols are vectorized versions of product or brand logos. The
+copyright of those is owned by the respective companies (Apple, Microsoft,
+Kenwood), and each of those may have some opinions on how the logos are
+used.  Please check for yourself if you can use them or not.
+
+In the list below I try to summarize the licensing status for each symbol.

+  * Vectorized versions are designed to look similar
+  * Licensing: Unknown
+* *OH7LZB* - Original vector design by Heikki Hannikainen, OH7LZB
+  * Different enough (by author's opinion) to make it a new original work,
