If you are kind enough to submit patches, first of all, thanks. If you do, please _please_ send git patches made against a recent version of the tree. See . When submitting diffs, please indicate what they are for (that is, please indicate the nature of the bug they fix or the system and version which requires the change). You can submit patches by email to bug-cssc@gnu.org. However, if they are large, we may need you to assign copyright in those changes to the Free Software Foundation before applying them.
