More complete documentation will reside in\n./doc, although such is currently in a very early state\n\n\nDEPENDENCIES\nlibelf\n  widely available with a couple different implementations. I\n  recommend the one from Red Hat at\n  https://fedorahosted.org/elfutils/. The FSF version\n  (http://directory.fsf.org/project/libelf/) which is the default\n  available to gentoo users, does not seem to be fully compatible.\nlibdwarf\n  you can get the latest version of libdwarf from\n  http://reality.sgiweb.org/davea/dwarf.html. \nlibunwind\n  http://www.nongnu.org/libunwind/\nlibreadline\n  http://www.gnu.org/software/readline/\nbison\n  http://www.gnu.org/software/bison/\nflex\n  http://flex.sourceforge.net/\n\nBUILDING\n./configure\nmake\n\nNote that flex and bison (as well as gcc, of course) are required to\nbuild Katana.\n\nmake\n./install libdwarf.so DEST\n\nTESTING\nTo make sure katana works:\nmake check\n\nNote that at present this only tests the hotpatching features of katana\n\nUSAGE\n  Katana presently has two main functions\n  HOTPATCHING\n    To generate a patch file, run\n    katana -g [-o OUT_FULE] OLD_OBJECT_TREE NEW_OBJECT_TREE EXEC\n    (EXEC is the name of the executable file whose process will be patched)\n\n    To patch a process run\n    katana -p PATCH_FILE PID\n\n  ELF/DWARF Manipulation\n    Documentation has not yet been written.
