The name ua is derived from the Hungarian word ugyanaz meaning the same.
The development of ua was motivated by the disturbingly often recurring
event of waiting too long for a shell script using sorts, md5sums, diffs
and the like to finish finding identical files. While there are many tools
out there, we needed a tool that can ignore white spaces and runs quite fast.
