Re: Re : RTSA vs. OO approach to RTE design

[Joseph Wisniewski <wisniew@primenet.com>]

Side note. Over the years I have seen Ada projects claim that they use
"OO" and have not a clue what that means to Ada projects that never
use the term "OO" but have VERY good package interfacing scheme. The
answer to the following question tells me more about the understanding
of what OO is supposed to do than the use of any methodology or tool.

"Tell me how you decided to design your packages"
