# Order of the official installation procedure:
# You download .zip from blackmagicdesign site.
# Then you unpack it. Two files are inside: pdf and run.
# In pdf there is a link to dedicated centos iso installer with dr, which we may use for tests.
# .run file is actually AppImage. It starts AppRun file, which calls "installer" executable.
# For some reason they made it binary, so we cannot see what else it does. But here is order of its actions:
# - run scripts/pre_install.sh
# - copy all files except AppRun and .DirIcon to /opt/resolve
# - run scripts/post_install.sh
# So this pkgbuild is remake of these actions.

Way too long and complex for something that is be easier to script than previously.

It repeats steps of the installer script except some things that pacman handles automatically.
Previous script was with errors and was done for other type of installer (it was sh, not it is run, which actually is appimage).
