The bastard disassembler

The bastard disassembler is a disassembler written for x86 ELF targets on Linux. Other file formats/CPUs can be 'plugged in'. It has a command-line interface and is meant to be used as a backend or engine. Support for controlling the disassembler via pipes is provided. Note that this disassembler does not rely on libopcodes to do its disassembly. Rather, the 'libi386' plugin is a standard .so that can be reused by other projects.

          Release Notes: This is very much a bugfix, "caveat compilor" release. The API function names have changed, and are now broken up into files in include/api. The docs have been munged with sed to reflect this, but no real attempt at redocumenting has been made for this release. Thus, in all cases where the documentation seems inaccurate, refer to the source and .bc scripts. Further, there is an experimental UI in src/sob. The UI was created with Glade and is far from complete. However, it is somewhat useable and permits niceties like DB browsing. The UI is to be considered extremely unsupported.

            Release Notes: Bugs in the install process have been fixed (EiC and the DBs now behave correctly). ~/.bastard directory was added to store target DBs as they are being worked on. config.db was replaced with a ~/.bastard/cmd_history. Support for ~/.bastard/bastard.rc and /etc/bastard.rc added. CLI access to options using "SET" and "SHOW" was refined.
