# This script's purpose is to ease compiling qTox for users.
#
# NO AUTOMATED BUILDS SHOULD DEPEND ON IT.
#
# This script is and will be a subject to breaking changes, and at no time one
# should expect it to work - it's something that you could try to use but
# don't expect that it will work for sure.
#
# If script doesn't work, you should use instructions provided in INSTALL.md
# before reporting issues like “qTox doesn't compile”.
#
# With that being said, reporting that this script doesn't work would be nice.
#
# If you are contributing code to qTox that change its dependencies / the way
# it's being build, please keep in mind that changing just bootstrap.sh
# *IS NOT* and will not be sufficient - you should update INSTALL.md first.
