Why does reposurgeon generate .gitignore files<ref>http://www.catb.org/~esr/reposurgeon/dvcs-migration-guide.html</ref>? Partly because it converts <code>svn:ignore</code> properties. Partly because some tools ([[git-svn]]) introduce .gitignore files to the svn repo. I also believe it may have to do with empty directory commits.<ref>https://stackoverflow.com/questions/22822020/convert-an-svn-repository-to-git-with-reposurgeon-without-creating-gitignore-fi</ref>
