 From page 375 of Programming in D.
```
import std.stdio;

void main() {
     do_something;
}

deprecated("Please use doSomething() instead.")     // No 
trailing semicolon, please
alias do_something = doSomething;

// void do_something() {
//     writeln("Using Eiffel snake_case, which doesn't pass D 
language style guide");
// }

void doSomething() {
     writeln("Using clean, mother approved camelCase styling which 
passes the D language style guide");
}
```

When running
```
dub build -dw
or
dub build -de
```

I get this error message, which makes no sense.
```
Error Error processing arguments: Can't parse string: bool should 
be case-insensitive 'true' or 'false'
              Run 'dub help' for usage information.
```

Kindly provide some sample code that properly handles deprecated.
I'm running on Windows DMD 2.111.0

As far as I can tell from the limited information provided, this 
error message stems from DUB. Please double-check or post your 
project’s DUB package recipe.

Also, these commands probably don’t do what you think they do.

 ```
 -d  --debug=VALUE     Define the specified `debug` version 
 identifier when
                        building - can be used multiple times
 ```

What should be the exact commands for
1. ignore deprecation
2. warn deprecation
3. error deprecation ?

The clean approach would be to add build requirements to your 
package recipe:
<https://dub.pm/dub-reference/build_settings/#buildrequirements>

"allowWarnings" → Warnings do not abort compilation
"silenceWarnings" → Don't show warnings
"disallowDeprecations" → Using deprecated features aborts 
compilation
"silenceDeprecations" → Don't show deprecation warnings

Alternatively, you can provide a DFLAGS environment variable to 
DUB which contains paremeters to be passed through to the 
compiler, i.e. `DFLAGS="-de" dub build`.
