printing all except final frozen contents to stderr (not quite usefull yet as fabric prints its logs to stdout currently)
bumped version
added --cache option
hiding fabric commands so stdout can be directly piped to a requirements file
stronger algorithm for finding distros names and reorganized source tree a bit
added an option to cache requirements files dependencies
printing cache hits to stderr
manage different versions of the same package in different requirements, by selecting the highest version
refactor
output is sorted alphabetically by distro name
avoiding duplicate packages in output
forgot to save operations.py
added --use-mirrors option
added options to control fabric's timeout and connection_attempts fabric options
added an option to specify pip executable
Support for pip 1.5.x

Added an option to build wheel packages

Added --allow-external --allow-all-external and --allow-insecure, passed
to pip
Wheel packages are now built in the same step as downloads, before updating the cache. This way if a build fails the cache is not updated and the build can be relaunched without modifying the requirements file.
added an option to exclude dependencies from frozen requirements
putting a DO NOT EDIT note in frozen requirements
