1.66      jufi       61: <a href="http://www.cs.utah.edu/projects/flux/lites/html">Lites</a> and
1.68      jufi       62: <a href="http://www.mklinux.org">MkLinux</a>.
1.38      mickey     63: These two sources were a major supply of information and
                     64: code for initial development of the OpenBSD/hppa port.

                     68: One of the major direct benefits from previous porting efforts
1.74      miod       69: (besides the code, of course) was support for HP PA-RISC in GCC and
                     70: binutils, which allowed quick building of a cross-tools environment

                     76: family, which actually resulted in some proprietary documentation
