DOS ain't dead

lpaq1 by Matt Mahoney (July 24, 2007) is a "lite" version of PAQ, about 35 times faster than paq8l but producing files about 10% bigger. It is a file compressor (not an archiver). It has options selecting from 6 MB to 1.5 GB memory.

P.S. The Win32 .EXE (sadly) needs MSVCRT.DLL, so I instead compiled it myself using DJGPP / G++ 4.1.2 and then UPX'd it (67k). Works great! :)
