See also http://pdos.csail.mit.edu/6.828/2012/v6.html, which\nprovides pointers to on-line resources for v6.\n\nxv6 borrows code from the following sources:\n    JOS (asm.h, elf.h, mmu.h, bootasm.S, ide.c, console.c, and others)\n    Plan 9 (entryother.S, mp.h, mp.c, lapic.c)\n    FreeBSD (ioapic.c)\n    NetBSD (console.c)\n\nThe following people have made contributions:\n    Russ Cox (context switching, locking)\n    Cliff Frey (MP)\n    Xiao Yu (MP)\n    Nickolai Zeldovich\n    Austin Clements\n\nIn addition, we are grateful for the patches contributed by Greg\nPrice, Yandong Mao, and Hitoshi Mitake.\n\nThe code in the files that constitute xv6 is\nCopyright 2006-2012 Frans Kaashoek, Robert Morris, and Russ Cox.\n\nERROR REPORTS\n\nIf you spot errors or have suggestions for improvement, please send\nemail to Frans Kaashoek and Robert Morris (kaashoek,rtm@csail.mit.edu). \n\nBUILDING AND RUNNING XV6\n\nTo build xv6 on an x86 ELF machine (like Linux or FreeBSD), run \"make\".\nOn non-x86 or non-ELF machines (like OS X, even on x86), you will\nneed to install a cross-compiler gcc suite capable of producing x86 ELF\nbinaries.  See http://pdos.csail.mit.edu/6.828/2012/tools.html.\nThen run \"make TOOLPREFIX=i386-jos-elf-\".\n\nTo run xv6, you can use the Bochs or QEMU PC simulators. Bochs makes\ndebugging easier, but QEMU is much faster. To run in Bochs, run \"make\nbochs\" and then type \"c\" at the bochs prompt. To run in QEMU, run\n\"make qemu\".\n\nTo create a typeset version of the code, run \"make xv6.pdf\".  This\nrequires the \"mpage\" utility.
