Well, so far I've managed to port both hsz and unhsz to C/C++ (C for hsz, and C++ for unhsz) and I'm in process of porting xhsz (the linux graphical user interface) to C++ and Qt--I was going to use GTK+, but I couldn't figure out how to get it to compile correctly and there only seems to be the one tutorial for it. I think that I'll go ahead and re-release the pre_gamma of Html SymboliZe so that Linux users will be able to enjoy the fixed icon and stuff like that without having to switch to the new GUI, which may or may not appeal to some.
That's all I got for now.
