Hello Kevin.

1)
The license dialog comes up once when the user runs a new version of xsane, it does
not come up every time.

2)

not prohibited to display the license.

3)
The reason why I enforce the accept license dialog after each update or new installation
of xsane is not the license itself, it is the part:

	This program is distributed in the hope that it will be useful, but
==>	WITHOUT ANY WARRANTY; without even the implied warranty of
	MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE

It is (or at least may be) relevant in some contries that the user accepts this
exclusion of warranty, otherwise I (the author) could be made responsible for any
damage (e.g xsane could destroy the scanner hardware, or it could remove important
files) that is caused by the program.

4)
>From the view of the GPL you are free to change xsane that it does not display
the license any more. But in this case you have to add your name to the version
of xsane and document that you have removed the license dialog. If this xsane
version causes any damage you propably can be made responsible for this damage
and you may be forced to pay compensation for the damage.



If there is a user that complains about this dialog I say:
this is the price you have to pay for the software I created.

Please do not publish an xsane version that does not show the license
dialog.

Bye
Oliver
