r"""
|
|
A simple script to update the requirements files from a global set of
|
|
allowable requirements.
|
|
|
|
The script can be called like this:
|
|
|
|
$> python update.py ../myproj
|
|
|
|
Any requirements listed in the target files will have their versions
|
|
updated to match the global requirements. Requirements not in the global
|
|
files will be dropped.
