+# Tab completion for FlightGear command line options. To use it put
+# this in your ~/.bashrc file:
 #
-# 1. define $FG_HOME (or accept the default "$HOME/.fgfs/")
+#   export FG_HOME=$HOME/.fgfs/
+#   [ -e $FG_HOME/fg-completion.bash ] && source $FG_HOME/fg-completion.bash
 #
-# 2. source this file from your ~/.bashrc:
-#
-#      [ -e $FG_HOME/fg-completion.bash ] && source $FG_HOME/fg-completion.bash
-#
-__fgfs_scriptname="fg-completion.bash"  # adapt this if you renamed this script!
+# Defining FG_HOME is only required if you don't like the default
+# "$HOME/.fgfs/". The script doesn't offer all available airports
+# for the --airport option, but only those listed in a file
+# $FG_HOME/airport.list if available, or a short default list otherwise.
