Most of the emacs programs don't have a `main' function (as in C
programs). First you load a file, then you run a command.
For a fun example, consider tetris.
,----
| First you load the file with
| M-x load-library RET tetris RET
|
| Then you run the tetris program with
| M-x tetris TAB TAB (there are two tabs)
|
| So now you know what all you could do. If you click on tetris with a
| mouse the game will start.
|
| Now you find that you are losing fast and you want to stop the game. So
| again you do
| M-x tetris TAB TAB
|
| You click on tetris-end-game and you are done.
`----
,----
| For another fun example, you can do
| M-x butterfly RET
`----
,----
| Now you do
| M-x list-command-history RET
|
| You will see what all you did. You will see lines like
|
| (tetris)
| (tetris-end-game)
`----
,----
| For automatically running tetris, create a file with name .emacs in your
| home directory and copy paste the first line.
|
| (tetris)
|
| and then start emacs normally.
`----
You are done.
Now you have to do
C-h t
and read the manual.
