Software Development
Software development will be accomplished by using the freely available GCC (Gnu Compiler
Collection). This will give the purchaser an opportunity to compile code for them and to make changes
to the provided code to test other configurations. GCC was chosen because it can be obtained free of
charge. There are also versions available for most modern programming environments.
