I would prefer to see it just: - Find a source distribution (the variants you specified) on the given server which matches the supplied version string, using the same semantics as the current 'pkg_resources' constraints. - Unpack the source distribution to a temp directory. - cd into that directory and use sys.executable to invoke 'setup.py install'. Any extra command-line arguments beyond those used to find the source distribution would be passed on to the 'install' command, which would allow alternate locations, etc. That makes the installation as much like a manual one as possible, and means that existing pacakges will be installable whether or not they know about setuptools, etc. - -- =================================================================== Tres Seaver +1 540-429-0999 [EMAIL PROTECTED] Palladion Software "Excellence by Design" http://palladion.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFH3sDr+gerLs4ltQ4RAhjWAKCbFP87mJN4UnVt0pzDs81JovVpoACdGI7A tohpRJnXah0/QnyQeYiqoYY= =9Cif -----END PGP SIGNATURE----- _______________________________________________ Distutils-SIG maillist - Distutils-SIG@python.org http://mail.python.org/mailman/listinfo/distutils-sig
