Minimalistic README for the binutils-based disassembly tool


Well, basically I got fed up with binutils themselves refusing to touch
a binary file (or any vaguely smelly elf files), so I broke out their
libs and wrote my own interface to it all =). The usage is simple. The
first parameter is a filename of a binary file, presumably containing
SH4 binary code. The second parameter is the VMA (virtual memory address)
of the code, which is where it expects to be running in memory. A 1ST_READ
would expect to be at 8c010000, the BIOS would expect 00000000 (though
that one's a bit more complicated =), etc. A nicely formatted disassembly
similar to dcdis.exe for Windows will be dumped to the stdout. The main
difference is that the columns are lined up, thanks to libopcodes, and 
the hex numbers are 0xdeadbeef instead of H'DEADBEEF.

The included binary (if you can't get it to compile, no big surprise, it
took me a while too =) is for Linux glibc2.1. No weird lib dependencies
so it ought to work under, e.g., the FreeBSD emulation too.
