comparison svnwrap/svn_swig_wrapper.py @ 301:79440ed81011

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Allow specifying a revision to stop at using the -H flag. This is useful for converting repositories which have been deleted or renamed, such as llvm-gcc-4-2 in the LLVM repositories which was renamed to llvm-gcc-4.2 shortly after its creation. Also, consolidate the two places in svn_swig_wrapper.py where a default chunk size is specified to one, single variable declaration.
