#!/bin/sh
#
# This file is an abomination. It executes as both a shell script and a python
# script, and does the same thing in both cases.
#
# Note that this script uses bash syntax but the shebang is `#!/bin/sh` on
# purpose. This is because the bash code only runs on MSYS and `/bin/sh` is
# bash there. macOS will stop shipping bash at some point (post-Catalina), so
# we should not use `#!/bin/bash` as the shebang. Current code is compatible
# on non-MSYS platforms with: bash, dash, zsh.
#
# This is needed because on Windows, python3 is actually `py -3` since all
# Python installations have `python.exe`. We used to use `python3` in the
# shebang, but then Windows folks couldn't use `./cerbero-uninstalled` and had
# to call `py -3 ./cerbero-uninstalled` or `python ./cerbero-uninstalled`
# depending on their python installation.
#
# Now we automatically use `py -3` or `python3` depending on the system.
#
# For backwards-compatibility, we now support all those variants.
