# install.sh — copy the X4MP extensions into your X4 game's extensions folder.
#
# Usage:
#   X4MP_GAME_DIR="/path/to/X4 Foundations" ./install.sh
#   ./install.sh "/path/to/X4 Foundations"
#   ./install.sh            (prompts for the path)
#
# It copies x4native/, x4mp/, x4mp_stream/ into "<game dir>/extensions/".
# Existing files of the same name are overwritten; other extensions are left
# untouched.
