+#!/usr/bin/env python3
+"""
+kpxc-search: put a query into the search box of an already running KeePassXC
+via AT-SPI (the Linux accessibility bus). Works on X11 and Wayland.
+
+Usage:  kpxc-search 'u:alice url:ssh://db01.example.com' [--timeout 60] [--debug]
+
+Requirements:
+  - PyGObject + the Atspi typelib (at-spi2-core)
+  - KeePassXC started with QT_LINUX_ACCESSIBILITY_ALWAYS_ON=1
+
+Speed: every AT-SPI property read is a D-Bus round trip, so walking the widget
+tree is the slow part. After the first successful run the script remembers the
+search box's position in the tree (in $XDG_RUNTIME_DIR/kpxc-search.json) and
+goes straight there next time, verifying it is still the right widget. It falls
+back to the full walk only if that check fails (layout changed, new version...).
+
+Exit codes: 0 = query set, 1 = KeePassXC not found, 2 = search box not found
+(e.g. database still locked and --timeout expired).
