+Tests for the --stop flag for `hg evolve` command while resolving orphans
+=========================================================================
+
+The `--stop` flag stops the interrupted evolution and delete the state file so
+user can do other things and comeback and do evolution later on
+
+This is testing cases when `hg evolve` command is doing orphan resolution.
+
+Setup
+=====
+
+  $ cat >> $HGRCPATH <<EOF
+  > [alias]
+  > glog = log -GT "{rev}:{node|short} {desc}\n ({bookmarks}) {phase}"
+  > [extensions]
+  > EOF
+  $ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH
+
+  $ hg init stoprepo
+  $ cd stoprepo
+  $ echo ".*\.orig" > .hgignore
+  $ hg add .hgignore
+  $ hg ci -m "added hgignore"
+  $ for ch in a b c d; do echo foo > $ch; hg add $ch; hg ci -qm "added "$ch; done;
