ARGL ! There are two options called "negative". While this is of course no<br>
|
||
problem for a GUI type app, as having to checkboxes is no problem, it _is_<br>
|
||
a problem for commandline apps.<br>
|
||
<p>
|
||

|

<p>
|
||
Yes. As it is talking about the first one ... <br>
|
||
<p>
|
||
<i>> I wonder if the fact that both options get the same "--negative" name </i><br>
|
||

It rather considers the first one being in charge for all interaction with<br>
|
||
it. But you basically got the point.<br>
|
||
<p>
|
||
<i>> (would it be a bug ?). </i><br>
|
||
<p>
|
||
It is a backend bug to have two options with the same name. Maybe we should<br>
|
||
document that in the SANE specs ... ???<br>
|
||
<p>
|
||
Bug the backend maintainer about that. One option should be renamed.<br>
|
||
