Suggested Projects for Improving GNU `diff' and `patch'
=======================================================

   One should be able to use GNU `diff' to generate a patch from any
pair of directory trees, and given the patch and a copy of one such
tree, use `patch' to generate a faithful copy of the other.
Unfortunately, some changes to directory trees cannot be expressed using
current patch formats; also, `patch' does not handle some of the
existing formats.  These shortcomings motivate the following suggested
projects.

* Menu:

* Changing Structure 	Handling changes to the directory structure.
* Special Files 	Handling symbolic links, device special files, etc.
* Unusual File Names 	Handling file names that contain unusual characters.
* Arbitrary Limits 	Patching non-text files.
* Large Files 		Handling files that do not fit in memory.
* Ignoring Changes 	Ignoring certain changes while showing others.
