+This patch adds backward-compatibility support for the --acls option.
+Since the main release has never had ACL support, the trunk doesn't
+need this code. If you want to make rsync 3.0.x communicate with an
+older (patched) release, use this.
+
To use this patch, run these commands for a successful build:
patch -p1 <patches/acls.diff
- ./prepare-source
- ./configure --enable-acl-support
+ ./configure (optional if already run)
make
-See the --acls (-A) option in the revised man page for a note on using this
-latest ACL-enabling patch to send files to an older ACL-enabled rsync.
