    # --------------------( SYNOPSIS )--------------------
    # Linux-based installer for the "Long War Rebalance" XCOM mod.
    #
    # --------------------( INSTALLATION )--------------------
    # Copy this script into the top-level directory to which you unzipped the
    # contents of the "Long War Rebalance" zip archive and run that script to
    # install "Long War Rebalance": e.g.,
    #
    # 1. Download both this installer and the "Long War Rebalance" zip archive into
    # the current directory.
    # 2. Unzip this archive:
    # unzip 'LW Rebalance '*.zip
    # 3. Copy this installer into the unzipped directory:
    # cp install_linux.bash 'LW Rebalance '*/
    # 4. Run this script to install "Long War Rebalance":
    # bash 'LW Rebalance '*/install_linux.bash
    #
    # --------------------( USAGE )--------------------
    # $ bash install_linux.bash [XCOM_INSTALL_DIRECTORY]
    #
    # This script optionally accepts the absolute or relative dirname of the
    # top-level installation directory for "XCOM: Enemy Unknown." When unpassed,
    # this argument defaults to the typical Steam installation directory (i.e.,
    # "~/.steam/steam/steamapps/common/Xcom-Enemy-Unknown").
    #
    # --------------------( EXAMPLES )--------------------
    # * Install "Long War Rebalance" to the typical Steam installation directory:
    # bash install_linux.bash
    # * Install "Long War Rebalance" to a custom installation directory:
    # bash install_linux.bash ~/Games/XCom_Enemy_Within
