A UCM component is simply a directorytree made up of files and directories that has one component root directory.
一个UCM构件简单来说,是一个由同一个构件根目录下的文件和目录组成的目录树。

Imagine a scenario in which you want to traverse a directorytree recursively, stopping at each file anddirectory under that treeand having your own callback methods invoked for each entry found.
There are a few other reports: One shows the average file size, another shows how the code is distributed over the directorytree, and another shows which files were revised the most.
