`setup.py --requires` is mostly useless. It only reports back entries from the `requires=` argument to setup() supported by distutils. This only tracks the names of other modules that a module needs to import, and is being phased out as not particularly useful. It's not in any way tied to `install_requires` which is a feature added by setuptools. As for "requirements.txt", you might mean "requires.txt" which is a file added to the .egg_info directory when you run the `setup.py egg_info` command on a setuptools-enabled package. Pip has its own code for reading information from files out of .egg_info. I believe there are other libraries like pkginfo [1] that do this. > It's for a Python dependency management/monitoring system I am writing so > hopefully would benefit the overall community. Sounds intriguing!
