Subsequent articles will cover a subset of the Mach-O file format, then generating Mach object files suitable for linking with ld or gcc to produce working executables. A basic knowledge of Ruby and C are assumed. You can likely wing it on the Ruby side of things if you know any similar languages.

+Meet [CStruct](https://github.com/samsonjs/compiler/blob/20c758ae85daa5cfa0ad9276c6633b78e982f8b4/asm/cstruct.rb#files), a class that you can use to describe a binary structure, somewhat similar to how you would do it in C. Subclassing CStruct results in a class whose instances can be serialized, and unserialized, with little effort. You can subclass descendants of CStruct to extend them with additional members. CStruct does not implement much more than is necessary for the compiler. For example there is no support for floating point. If you want to use this for more general purpose tasks be warned that it may require some work. Anything supported by Array#pack is fairly easy to add though.
