; This script should be compiled with e.g.:
;     makensis -NOCD -DTARGET=gs900w32 -DVERSION=9.00 psi/nsisinst.nsi
 

; Significant differences with the older winzipse-based installer are:

; The Winzipse-based installer opens README on successful install.
; Besides the installation directory, the name of the short-cuts and 
; whether it applies to "All Users" are optional, and so is whether
; to generate a CJK cidfmap, (default to NO for silent installation).

; The NSIS-based installer does not open README on successful install; 
; only whether to generate a CJK cidfmap (default to YES for silent
; installation) is optional; short-cuts are for "All Users". On the other
; hand, it removes the short-cuts on Uninstall (which the Winzipse-based
; installer doesn't do) and also does not leave behind empty directories.

; Requirements:
;     NSIS 3.0+
;     EnVar plug-in from https://nsis.sourceforge.io/EnVar_plug-in

; Newer nsis releases deprecate ansi encoding, require Unicode
Unicode True
