Application description
Describes the architecture of the application.
In ilodiet.cpp , the main
part of the application starts by declaring the environment and terminates
by calling the method end for that environment.
The code in between is encapsulated in a try
block that catches all Concert Technology exceptions and prints them
to the C++ error stream cerr . All other
exceptions are caught as well, and a simple error message is issued.
The first action of the program is to evaluate command-line options
and call the function usage in cases of
misuse.
Note:
In such cases, an exception is thrown. This practice
makes sure that env.end is called before
the program is terminated.
