# This installs two files, app.exe and logo.ico, creates a start menu shortcut, builds an uninstaller, and
# adds uninstall information to the registry for Add/Remove Programs
# To get started, put this script into a folder with the two files (app.exe, logo.ico, and license.rtf -
# You'll have to create these yourself) and run makensis on it
# If you change the names "app.exe", "logo.ico", or "license.rtf" you should do a search and replace - they
# show up in a few places.
# All the other settings can be tweaked by editing the !defines at the top of this script
