+# Install the PSP Preservation Tool to a system prefix.
+#
+# FHS-friendly layout:
+#   $PREFIX/bin/psp-preserve              symlink -> payload binary
+#   $PREFIX/lib/psp-preserve/             app payload (binary + lib/)
+#   $PREFIX/share/applications/           desktop entry
+#   $PREFIX/share/icons/hicolor/256x256/apps/  app icon
+#
+# The PyInstaller onedir build keeps the executable and its `lib/` contents
+# directory side by side, so both live under $PREFIX/lib/psp-preserve/ and a
+# symlink exposes the binary at $PREFIX/bin/psp-preserve.
+#
+# Usage (run from inside the extracted tarball):
+#   sudo ./install.sh                 # install to /usr/local (default)
+#   sudo ./install.sh --prefix=/usr   # install to /usr
+#   sudo ./install.sh --uninstall     # remove from the default prefix
+set -eu
