--extensions (-x) ARG --force --incremental --revision (-r) ARG --use-merge-history (-g) --verbose (-v) --xml
If you want to see blame-annotated source for
            readme.txt in your test
            repository:
$ svn blame http://svn.red-bean.com/repos/test/readme.txt
     3      sally This is a README file.
     5      harry You should read this.
Even if svn blame says that Harry
            last modified readme.txt in revision
            5, you'll have to examine exactly what the revision
            changed to be sure that Harry changed
            the context of the line—he may
            have adjusted just the whitespace.
          
If you use the --xml option, you can
            get XML output describing the blame annotations, but not
            the contents of the lines themselves:
$ svn blame --xml http://svn.red-bean.com/repos/test/readme.txt <?xml version="1.0"?> <blame> <target path="sandwich.txt"> <entry line-number="1"> <commit revision="3"> <author>sally</author> <date>2008-05-25T19:12:31.428953Z</date> </commit> </entry> <entry line-number="2"> <commit revision="5"> <author>harry</author> <date>2008-05-29T03:26:12.293121Z</date> </commit> </entry> </target> </blame>
