OllyDbg 1.10 is a 32-bit assembler-level analyzing debugger for
Microsoft(R) Windows(R) with intuitive interface. Emphasis on binary
code analysis makes it particularly useful in cases where source is
unavailable. It predicts contents of registers, recognizes procedures,
API calls, switches, tables, constants and strings, locates routines
from object files and libraries, allows custom labels and comments in
disassembled code, writes patches back to executable file and more.

You can write your own plugins - dynamic link libraries that attach to
OllyDbg and provide new functions. Plugins can insert entries into
pop-up menus of OllyDbg windows, process keyboard shortcuts, save data
to .ini and .udd files and call more than 170 functions exported by
OllyDbg. Plugin interface is free - provided that you distribute your
plugins free of charge.

Installation is not necessary. Simply create new directory and unpack
the contents of the zip archive. No installation means also no trash in
registry and system directories. You even can start OllyDbg from the
floppy disk.

Distribution includes plugins bookmark.dll (bookmarks in Disassembler)
and cmdline.dll (command line).
