Make 2004/burley fix more like original
The code can recursively call main() as long by changing the name of the argv and by a cast in the call. Updated Makefile to disable a new warning. Improved index.html file.

This is a [draw poker](https://en.wikipedia.org/wiki/Draw_poker) program. You
|
||||
start with $100. Input alternates between your bet and which cards to keep.
|
||||
Example:
|
||||
|
||||
```
|
||||
5 <== you enter a bet of $5 (defaults to $1)
|
||||
J Q J 9 5 <== your hand is Jack of Clubs, Queen of Hearts,
|
||||
C H D S C Jack of Diamonds, 9 of Spades, 5 of Clubs
|
||||
123 <== you enter which cards you want to keep
|

(enter 0 to 5 digits between 1 and 5)
|
||||
J Q J J Q <== your new hand is Jack of Clubs, Queen of Hearts,
|

C H D S C Jack of Diamonds, Jack of Spaces, Queen of clubs

||||
$145 (45) <== Your new balance is now $145. You had a Full House
|
||||
so your payoff is 9 times your bet == 45
|
||||
```
|
||||
### Example:
|
||||
|
||||
Here is an example.
|
||||
|
||||
First, enter your bet (say `5`) (for $5, defaults to $1). You might then see
|
||||
something like:
|
||||
|
||||
> J Q J 9 5<br>
|
||||
> C H D S C
|
||||
|
||||
That indicates your hand is Jack of Clubs, Queen of Hearts, Jack of Diamonds, 9
|
||||
of Spades and 5 of Clubs.
|
||||
|
||||
Now enter what cards you want to keep (enter 0 to 5 digits between 1 and 5).
|
||||
Let's say you want to keep 1, 2 and 3 so you enter `123`. You should see
|
||||
something like the following after you hit enter:
|
||||
|
||||
> J Q J J Q<br>
|
||||
> C H D S C
|
||||
|
||||
which tells you that your new hand is Jack of Clubs, Queen of Hearts, Jack of
|
||||
Diamonds, Jack of Spaces and Queen of clubs. You might now see something like:
|
||||
|
||||
> $145 (45)
|
||||
|
||||
which tells you that your new balance is now $145. You had a Full House so your
|
||||
payoff is 9 times your bet == 45.
|
||||
|
||||
#### Payout:
|
||||
|
||||
The payout is according to "Vegas rules":
|
||||
|
||||
```
