CMakeLists.txt

#
# The destination field is often used to identify the manufacturer/model.
# These are not hardcoded into Dire Wolf.  Instead they are read from
# a file called tocalls.txt at application start up time.
#
# The original permanent symbols are built in but the "new" symbols,
# using overlays, are often updated.  These are also read from files.
#
# You can obtain an updated copy by typing "make data-update".
# This is not part of the normal build process.  You have to do this explicitly.
#
# The locations below appear to be the most recent.
# The copy at http://www.aprs.org/tocalls.txt is out of date.
