# PyInstaller's description of the build, shared by the AppImage, the disk
# image and the Windows setup. Run it through build-appimage.sh, build-dmg.sh
# or build-windows.ps1 rather than by hand: each of those has a few steps of
# its own on either side of this.
#
# A directory rather than a single file, on all three. Onefile unpacks itself
# into a temporary directory on every start, which for something a global
# shortcut is meant to bring up is a second of nothing happening, and for the
# AppImage it would be an unpacking inside an unpacking. The single file people
# download is the AppImage, the .dmg and the setup program; this only has to be
# tidy inside them.
