+SUMMARY = "Weston panel launcher entry for Visual Studio Code"
+DESCRIPTION = "Optional companion package for meta-vscode: appends a [launcher] \
+section to /etc/xdg/weston/weston.ini at install time so the VSCode icon \
+appears on the Weston panel. Pull in via IMAGE_INSTALL when the target image \
+ships a Weston desktop and should expose VSCode as a one-click launch."
