コンフィグレータ
USOを使う場合、システムコールやタイマー割込みを利用する
マイコンに合わせて記述しなければなりません。
見本となるファイルを用意し、コピー＆ペーストでシステムコール
とタイマー割込み等の貼付けでは、見落としが起きやすくなります。
見落としが少なくなるように、タスク数とファイル名を与えると
スケルトンのＣソースコードを生成するアプリケーションソフト
（コンフィグレータ）を用意しました。
マルチプラットホームを考え、Tcl/TkでGUIをもったコンフィグレータ
を作成します。
Tcl/Tkから、CUIのプログラムyconfig.exeを呼び出し、Cのソースコード
を作成します。
コンフィグレータGUI
- タスク数を、▲か▼のクリックで確定します。
- 緑のシート部分に、ファイル名を入力します。（拡張子は不要です。）
- makeボタンをクリックします。
- 終了は、EXITボタンをクリックします。
Tcl/Tkコンフィグレータコード
ファイル名は、「confuso2.tcl」です。
UNIXの場合は、１行目のファイルパスを環境にあわせてください。

CUIコンフィグレータ
従来のUSOで利用した内容を、一部修正しています。
システムコールの定義を、変更します。
また、タスク数は最大１６個と規定しているので
変数ready、suspend、waitqを符号なし１６ビットとします。
Windowsの場合は、コンパイル、リンクして「YCONFIG.EXE」を
作成します。この実行形式ファイルを、GUIである「confuso2.tcl」
と同じディレクトリに保存します。

Tcl/Tkのみのコンフィグレータコード
