/**
 * This represents one particular directory in the hierarchy of source
 * directory files.  We must scan the source directory to identify where the
 * related files have previously been copied.
 *
 * The tree is maintained in a case-insensitive manner, even on a non-Windows
 * system, since you might want to eventually check out the CVS tree onto a
 * Windows system--and if you do, you'll be sad if there are case conflicts
 * within the tree.  So we make an effort to ensure this doesn't happen by
 * treating two files with a different case as the same file.
