* Add 'autogen.sh' to ease the use of 'acr'
- Added USERCC and USEROSTYPE configuration flags
--with-compiler : select a compiler from mk/
--with-ostype : select a target OS (not required for ming32 f.ex)
* Add language bindings APIs from radare1
- Fix some issues from the ruby language binding
- Checks if file exists before slurping and causing a ruby segfault
- Added language destructor (.fini pointer)
* Rename str_clean into r_str_chop
* Initial work on the port for ming-w32
* Show flags instead of bytes in disassembly (smart disasm)
* New r_sys_{get|set}env (for portability issues
* Added flags -i and -l to radare2
* Fix warnings and random code cleanup
* Added r_flag_get_i
