Hello, To summarise this thread we have the following statments from the major contributors, which ought to have been enough. On Fri, 03 Aug 2007, Marcel J.E.

The manner in which Marcel J. E. Mol has kept historical data for the program needs to be commended, but it is (IMHO) not enough for DFSG-free-ness in 2007. The problem is that the code was developed from 1988 to 2003 by Marcel J. E. Mol under the original non-DFSG license. During this period a number of patches were provided --- a priori under the same (non-DFSG) license. The contributors are listed at the top of dvi2tty.c. Some of these patches may be irrelevant under gcc+glibc but the remaining contributors need to be contacted and the issue sorted out. Regards, Kapil. --
