# Create an Inno Setup installer on MSW. It requires MSYS.
#
# Example:
#
# distrib/msw/createsetup.sh
#
# Prerequisites:
#
# (1) Change VERSION to the desired wxWidgets version.
# (2) Change APPDIR to the root of a wxWidgets distribution containing
#     this script.
# (3) Change DESTDIR (if necessary) to a directory for creating the
#     the installer.
# (4) Change SETUPCOMPILER to where Inno Setup is installed.
# (6) Make sure 'unzip' is in your path.
# (7) Make sure wxMSW-x.y.z.zip and wxWidgets-x.y.z-CHM.zip are in
#     the directory $DESTDIR.
# (8) Run createsetup.sh.
#
# The necessary script files are:
#
# distrib/msw/createsetup.sh                  ; The main script
# distrib/msw/wxwidgets_in.iss                ; The input for making the .iss
