-# TODO: - fix date parsing (how hard can it be?)
+# TODO:
# - support integrations (at least p4i)
# - support incremental imports
# - create tags
# - instead of reading all files into a variable try to pipe from
-# - p4 print directly to stdout. need to figure out file size somehow
-# though.
# - support p4 submit (hah!)
# - don't hardcode the import to master
