# 20211124 bkw:
# - update for v0.3.0. upstream started using rust, so:
# - figure out how to use 'cargo vendor' so the build can be done
#   without network access. see mkvendored.sh for details.

# 20191231 bkw:
# - take over maintenance
# - update for v0.1.3
# - don't install useless INSTALL in doc dir
# - install demo source in doc dir
# - install tools/ordiag in /usr/bin
# - --disable-static
# - add doinst.sh with update-gdk-pixbuf-loaders
