+#!/usr/bin/env python2

+#

+# This Python script builds self-contained Linux packages, i.e. AppImages ( http://appimage.org/ ), of Swift.

+# It downloads required appimage tool that is executed at the end and an exculde list from the internet.

+#

+# Non-standard dependencies:

+# * plumbum ( https://plumbum.readthedocs.io/en/latest/ )

+# * click ( http://click.pocoo.org/5/ )

+#

+# They can be installed via `pip install plumbum click`.

+#

+# The script requires git, wget, readelf and objcopy to work and will fail if

+# they are not present.

+#

+# Just run ./Swift/Packaging/appimage/build_appimage.py and after it executed

+# there should be .appimage and .debug files in Packages/Swift.

+#

+# The appimage will be for the same architecture as the host architecture.

+# Pass `--qt5=False` to the tool to build against legacy Qt4.
