* main.lua replicates the functionality of makesyscalls.lua
* Individual files are generated by their associated module
* Modules can be called as standalone scripts to generate a specific
file
* Data and procedures are performed by objects instead of procedual code
* Bitmasks are replaced by declarative types
* Temporary files are no longer produced, writing is stored in memory
* Comments provide explanation to functions and semantics
