In addition to the aforementioned case for bug fix, there
is another example that TRICA contributed to save the
project. During the development, there was a critical change
to the software architecture. It was unavoidable to modify
already developed code. At that time, we reverted to the
latest stable snapshot stored in the Subversion repository.
What most developers needed was to keep developing. Only
a few developers were required to work on the changes. We
cannot imagine what would have happened if all the project
members had to find the location that had to be corrected,
modify the code, and integrate it again.
