+AOMedia Video 1 (AV1) is an Open Source video codec designed for
+video transmission over the Internet. AV1 is planned to surpass
+VP9 and also to eventually be a competitor with HEVC/H.265.
+
+This script builds the encoder aomenc, the decoder aomdec as well
+as shared libraries which can be utilised by recent versions of
+both FFmpeg and vlc.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
