Re: GPL2 or version for DjVu Reference Library
Dear Leon,
I write in response to your request that LizardTech amend certain language found in the
source code files of the DjVu Reference Library. Specifically, this language acts as an
addendum to the GNU General Public License, and grants a limited license to patents
related to the DjVu technology. This letter should serve as confirmation that LizardTecb
is amenable to changing the noted language, as provided below.
The existing source code contains the following notice:
