 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

 
* Internationalization Handling multibyte and varying-width characters.
* 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.
* Time Stamp Order     Outputting diffs in time stamp order.
* Ignoring Changes     Ignoring certain changes while showing others.
* Speedups             Improving performance.
