Scott-freeze

Keep requirements.in with unpinned or loosely pinned requirements, and let scott freeze them into requirements.txt for tests and deployment:

$ cat requirements.in
flask>0.9

$ scott-freeze requirements.in > requirements.txt

$ cat requirements.txt
# Generated file. Please do not edit manually
#
# `requirements.in` contains direct dependencies (and may be >version instead
# of ==version) This file is a list of dependencies and _their_ dependencies,
# completely frozen.  To generate this file, use scott-freeze
#

#     $ scott-freeze requirements.in > requirements.txt
