+Subject: [PATCH] Add --overwrite-existing option that overwrites existing
+ files
+
+Implement the --overwrite-existing option that, if supplied, will make
+installer overwrite any already existing package files instead of
+failing. With this flag, installer can be used in an idempotent manner,
+i.e. the same command can be executed multiple times with the same
+result:
+
+    python -m installer --overwrite-existing --destdir=tmp dist/*.whl
+    python -m installer --overwrite-existing --destdir=tmp dist/*.whl
