The original name of the application is "pv" but I chose to rename it to "xpv" to avoid clashes with the other package called "pv" (pipeviewer).
I discussed this issue with Stephan Ferraro (the author) and he agreed to have the package named "xpv".
Note that I also renamed the binary and the manpage to "xpv" instead of "pv".

This package requires SDL_gfx, which I also provide.
