# Version 1.04 - 26 Sept 2013
# Version 1.03 - 04 Sept 2013
# Version 1.02 - 01 Sept 2013
#
# Modified by Clément de l'Hamaide - 20130926
# * Disable phonebook.txt generation
#
# Modified by Geoff R. McLane - 20130904
# * Added strict and warnings, fixing all variables to comply
# * Added command line interface and 'help', but kept same defaults
# * Removed numerous substr($txt,0,-1) which truncated some string
# * Change 'chop' to the safer 'chomp'
# * Added heliport(16) and seaport(17) under an option switch
# * Added output of some stats of what was collected, and skipped
# * Added $trim_to_20 option to align the phonebook if desired
# * Replaced all tabs with ' ' to better align the code for readability
# * Added a trim_all($txt) to removed some unwanted line endings
# * Is compatible with FG 810 AND XP 1000 apt.dat files
