# parabola changes and rationale:
#  - rebranded to icedove
#  - added makedepends for branding: quilt mozilla-searchplugins imagemagick
#  - disabled tests, they break in an environment without network access.
#  - disabled geo-location
#  - removed nonfree search engines
#  - removed support for insecure chat protocols
