ToggleCapsLock. CSharp and Windows-batch Combined file.
(CapsLockを切り替えるアプリを作れるやつ＞＜) 


Please be sure to set line breaks
 to CR+LF before executing this batch file!

This file is both a batch file and C# source code,
 and can locate csc.exe and compile itself.
In principle, an error is inevitably displayed
 at the execution of the first line at compile time,
  but do not worry about it!

Running the generated ToggleCapsLock.exe should toggle CapsLock...

in Japanese description

実行前に必ず改行コードをCR+LFにしてください！！！＞＜

このファイルは、バッチファイル兼C#のソースコードになっていて、
実行するとcsc.exeを探し出して自らをコンパイルします＞＜
原理上、どうしてもコンパイル時の一行目の実行時にエラーが表示されますが、気にしないでください＞＜；

出来上がったToggleCapsLock.exeを実行するとCapsLockが切り替わるはず＞＜
