# NAME: findaps.pl
# AIM: There is a BIG findap[nn].pl - This is a SIMPLER version
# 19/05/2020 - Adjust for aptdat for Dell03 machine
# 2020-01-08 - review - maybe add xg output...
# 25/08/2015 - add to scripts repo
# 17/10/2014 - Change -i -c = no case change on name
# 16/10/2014 - Use later fgdata 3.3, thus add typ=100
# 14/04/2013 - Use later fgdata 2.10
# 19/05/2012 - Add more output according to verbosity
# 20/03/2012 - On help output the apt.dat file name
# 20/01/2012 - Output airport names correctly 'cased', and FIX sub not_on_track($)
# and add nav, fixes and airways loads
# 2011-12-12 - Also compiled and run in Ubuntu, and added -m num to change output count
