# Notes:
# 1. This script assumes you have all the dependencies
#   installed using HomeBrew.
# 2. Meant to be run from the parent dir
# 3. Uses appdmg (brew install npm, npm install -g appdmg)
# 4. need to install librsvg and then reinstall gdk-pixbuf
#   in brew to get svg support (or copy the pixbuf loader from
#   the Cellar of libtsvg to the Cellar of gdk-pixbuf) OR just install adwaita-icon-theme which
# installs both
# 5. do a `brew remove adwaita-icon-theme gtk+3 librsvg yelp-tools gdk-pixbuf` when done to check
# if it loads without these

# args:
# 1: version
# 2: zrythm source root dir
# 3: prefix where zrythm was installed
# 4: path to copy finished installer to
# 5: osx data dir (tools/osx)
# 6: normal prefix (where other programs are installed)
# 7: App name Zrythm or Zrythm (Trial)
# 8: App name Zrythm or Zrythm-trial
