- \class ArchiveExtractor
-
- \brief The ArchiveExtractor class is a base class for classes that
- know how to unpack a certain kind of archive file.
-
- The archive extractor contains a list of the filename extensions
- of the files that the archive extractor knows how to unpack.
-
- It maintains a static list of all the instances of ArchiveExtractor
- that have been created. It also has a static function for searching
- that list to find the archive extracter for a file with a certain
- extension.
- */
-
-/*!
- The constructor takes a list of filename extensions, which it
- copies and saves internally. This archive extractor is prepended
- to the static list.
- */

-/*!
- This function searches the static list of archive extractors
- to find the first one that can handle \a fileName. If it finds
- an acceptable extractor, it returns a pointer to it. Otherwise
- it returns null.
