I’m writing code for approximately ten years now and at some point the word “writing” became more important then “code”. I found out that it is easy to generate code but it is difficult to write code. Writing means creating something meaningful. Something that other human beings will read. The code is indeed sent to machines and they do understand ugly code. Not the same for humans though. An important part of our job is to make sure that our code is clear for other teammates.

That's a great article by Robert C. Martin. It's one of those articles that really may change something in your programming. The principle is called Open-Closed and it says:_SOFTWARE ENTITIES (CLASSES, MODULES, FUNCTIONS, ETC.) SHOULD BE OPEN FOR EXTENSION, BUT CLOSED FOR MODIFICATION._More about that here.

SWC file format is really useful when you want to transfer or to compact your ActionScript libraries. It is also used for exporting assets, which can be used later. Let's imagine that you want to create a .swc file for only small part of your application, i.e. pure .as files. I searched a lot for the fastest and easier solution and finally I think that the usage of compc.exe is the best option.
