# Cyberterm shell integration for zsh.

# Reports the working directory (OSC 7) and marks each prompt and command
# (OSC 133), which is what lets Cyberterm jump between prompts
# (Ctrl+Shift+Z / Ctrl+Shift+X) and remember exit codes. Harmless in other
# terminals: unknown OSC sequences are ignored.
