; Script generated by the Inno Setup Script Wizard.
; SEE THE DOCUMENTATION FOR DETAILS ON CREATING INNO SETUP SCRIPT FILES!
;
; This script creates an installable FlightGear package for Win32 using the
; "Inno Setup" package builder.  Inno Setup is free (but probably not open
; source?.)  The official web site for this package building software is:
;
;     http://www.jrsoftware.org/isinfo.php
;
; Note: Files root path is defined in the FgHarnessPath (in InstallConfig.iss)
;
; For example if You want to use X: drive as a root path 
; You can do this with the command below:
;
;     subst X: path_to_files
;
; For example:
;
;     C:\> subst X: F:\Path\to\FlightGear\root
;     C:\> subst X: F:\
;
; TRANSLATION NOTE:
;  - external i18n files HAVE to be UTF-8 with BOM encoded. Otherwise the installer can
;    not detect correct file encoding
;
; InstallConfig.iss example content:
;
;  #define FGHarnessPath "x:"
;  #define FGVersion "2020.4.1"
;  #define FGVersionGroup "2020.4"
;  #define OSGVersion "3.0.0"
;  #define OSGSoNumber "2"
;  #define OTSoNumber "3"
;  #define FGDetails "-nightly"
;  #define IncludeData "FALSE"
;  #define IncludeWeb "FALSE"
;
; Uninstall procedure with --uninstall flag:
;  executed by fgfs.exe (fg_init.cxx):
;  - removes all under the FG_HOME directory
;  - removes all from Download dir/Terrasync
;  - removes all from Download dir/Aircraft
