This generates the following for the TurboGears egg (telling it to use the optional SQLAlchemy stuff): # Autogenerated metadata from "requires.py /usr/lib/python2.4/site-packages/TurboGears-1.0.4.4-py2.4.egg-info SQLAlchemy" Provides: pythonegg(TurboGears) = 1.0.4.4 Requires: pythonegg(CherryPy) >= 2.3.0 Requires: pythonegg(CherryPy) < 3.0.0alpha Requires: pythonegg(DecoratorTools) >= 1.4 Requires: pythonegg(FormEncode) >= 0.7.1 Requires: pythonegg(PasteScript) >= 1.6.2 Requires: pythonegg(RuleDispatch) >= 0.5a0.dev-r2303 Requires: pythonegg(setuptools) >= 0.6c2 Requires: pythonegg(simplejson) >= 1.3 Requires: pythonegg(TurboCheetah) >= 1.0 Requires: pythonegg(TurboJson) >= 1.1.2 Requires: pythonegg(TurboKid) >= 1.0.4 Requires: pythonegg(SQLAlchemy) >= 0.3.10 Is the dash in the RuleDispatch version likely to cause problems? > > > > > Since this will be a far reaching change, should it be discussed on > > fedora-devel-list first or whether we want to do both parts? > > > > Could we simply put the script in a place where it's available to the > maintainer, so they can opt-in and have it generate the deps? > > > Hope this helps > Dave > > -- > Fedora-packaging mailing list > Fedora-packaging@xxxxxxxxxx > https://www.redhat.com/mailman/listinfo/fedora-packaging -- Fedora-packaging mailing list Fedora-packaging@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-packaging
