fileset
FileSets are used to select sets of files to copy. To use a fileset, the todir attribute must be set.
mapper
You can define filename transformations by using a nested mapper element. The default mapper used by <copy> is the identity mapper.
filterset
FilterSets are used to replace tokens in files that are copied. To use a FilterSet, use the nested <filterset> element.
filterchain
The Copy task supports nested FilterChains.
If <filterset> and <filterchain> elements are used inside the same <copy> task, all <filterchain> elements are processed first followed by <filterset> elements.
