93 | This class allows for writing small scripts, that can be compiled | |
94 | with AcLIC, to do all sorts of tests, quick prototyping, and so | |
95 | on. It has proven to be quiet useful. One can load more than | |
96 | one type of data in one derived class, to for example to make | |
97 | comparisons between hits and reconstructed points. See also the | |
98 | various scripts in @c FMD/scripts. | |
