--------------------------------------------------------------------
gxe-xxx.tar.gz を "tar -zxvf" で解凍し、"./configure && make" する。
コンパイルが成功したら、make install で /usr/local/binに 導入。

--------------------------------------------------------------------
Automake パッケージ 導入手順。
--------------------------------------------------------------------

    導入先フォルダーを変更する場合は ./configure を実行する前にconfigureを修正してください。
        html ヘルプは  "packagehelpdir",                省略値は /usr/local/share/gnome/help/gxe
        icon は        "packagepixmapsdir",             省略値は /usr/local/share/pixmaps/gxe
        bins は        ./configure --bindir=PATHで指定。省略値は /usr/local/bin

    (1)tar -zxvf gxe-v.rr.tar.gz    (v.rr : version)
    (2)cd gxe-v.rr
    (3)./configure
    (4)make
    (5)make install (rootで実行、ubuntuでは "sudo make install")
       次のbinだけが導入されます。これ以外のツールは自分でコピーしてください。
         gxe, xe, xprint, gxp, xfc, xdc
    (6)gnome-terminal ないし konsole 等の terminal emulator を開いて gxe ないし xe と入力する。
       ヘルプhtmlは立ち上げ後 第2行に "help" ないし "?" を入力するとブラウザーから観ることが出来ます。
    (7)ssh
       リモートでxe起動する場合、ssh(d)の設定をチェック。
           local :/etc/ssh/ssh_config
                      set "SendEnv LANG LC_*"
           remote:/etc/ssh/sshd_config
                      set "AcceptEnv LANG LC_*"
                      set "X11Forwarding yes"
                      xhost +local:username    local=local ip addr, username=your user id
                  xauth は導入済みか ?

       リモートでgxe起動する場合 -X オプションを指定する。
           ssh -X uid@remotehost
    (8)ショートカットキーの変更。(PF10 等が terminal emulator をパスしてxeに伝わるようにする)
       例えば Debian jessie 3.10 xfce では
    	ショートカットキー変更 F1=ヘルプ, F11=全画面, F10=メニュー
        	xfce4-terminal のメニューで
            	ヘルプ-->目次("F1" が表示されている)メニュー項目の上で"Del"キーを押す
            	表示-->全画面表示("F11"が表示されている)メニュー項目上で"Del"を押す
                編集-->設定(E)-->上級者(V), "メニューショートカットキーを無効にする"をオンにする

        通常DISPLAYはsshが制御するので必要ないはずだが
        リモートにxauth は導入済みか?
