# THE FLIGHTAWARE PIAWARE CLIENT SETUP SCRIPT

# JPROCHAZKA/PIAWARE_BUILDER REPOSITORY
# -----------------------------------------------------------------------------------
# I submitted a fix to support Debian Trixie and Ubuntu Noble Numbat to FlightAware's
# piaware_builder repository. Until the changes are merged into their Git reposiory
# the installation will be done using the fork I created along with the branch which
# contains the changes needed in order to build the package.
#
# https://github.com/flightaware/piaware_builder/pull/26

# TCLTLS-REBUILD
# -----------------------------------------------------------------------------------
# Along with PiAware, a version of tcltls maintained by FlightAware can be installed.
# This package is only needed for Debian Buster and possibly Ubuntu Focal Fossa. Once 
# these releases pass their end of life date the scripting will be removed.
#
# Debian Buster's end of life occured June 30, 2024 and is no longer supported.
# Ubuntu Focal Fossa's end of life is scheduled for April 2025.
