Splitdwarf uncompresses and copies the DWARF segment of a Mach-O
executable into the "dSYM" file expected by lldb and ports of gdb
on OSX.
Usage: splitdwarf osxMachoFile [ osxDsymFile ]
Unless a dSYM file name is provided on the command line,
splitdwarf will place it where the OSX tools expect it, in
"<osxMachoFile>.dSYM/Contents/Resources/DWARF/<osxMachoFile>",
creating directories as necessary.
