how do you prevent distutils from downloading and building packages without consent?

ok - john, gabriel, i've now removed setuptools, which is the area
that's problematic for many people.  however.... there's a feature of
setuptools which _is_ useful:

-        entry_points = {'console_scripts':[
-                       'pyjsbuild=pyjs.build:main',
-                       'pyjscompile=pyjs:main',
-                       ]},

whoops - those are now gone.

i have a command, bootstrap.py, which replicates that exact
functionality: it creates a customised pyjsbuild which can go in /usr/
bin or /usr/local/bin and it will add the library locations to
sys.path and also as a -D option to the pyjs main() function - it's a
little obscure, but works out fine.

e.g. if you specify no arguments, this gets auto-generated, in ./bin/
pyjsbuild :

#!/usr/bin/python

pth = '/home/lkcl/src/sf.pyjamas/svn-pyjamas/pyjamas'

import os
import sys
sys.path[0:0] = [
  pth,
  ]

import pyjs, sys
pyjs.path += [os.path.join(pth, 'library'),
os.path.join(pth, 'library', 'builtins'),
os.path.join(pth, 'addons'),
]
sys.argv.extend(['-D', pth])

import pyjs.build

if __name__ == '__main__':
    pyjs.build.main()

if you specify "python bootstrap.py /usr/share/pyjamas /tmp" you get,
in /tmp/bin/pyjsbuild:


#!/usr/bin/python

pth = '/usr/share/python'

import os
import sys
sys.path[0:0] = [
  pth,
  ]

import pyjs, sys
pyjs.path += [os.path.join(pth, 'library'),
os.path.join(pth, 'library', 'builtins'),
os.path.join(pth, 'addons'),
]
sys.argv.extend(['-D', pth])

import pyjs.build

if __name__ == '__main__':
    pyjs.build.main()


so, would you (or anyone else) happen to know how i can get setup.py
to run bootstrap.py to create these two scripts, in a way that's
compatible with the setuptools "entry_points" thing?  i.e. taking the
option of "--install-data" as the first argument to bootstrap.py and
the option of "--prefix" as the second argument.

i envisage it to be something like:


from bootstrap import create_commands
if distutils.XXXXX.cmd == "build":
    create_commands(distutils.XXXXXX.install_data_path,
                    distutils.XXXXXX.prefix)

but it all looks a bit hair-raising, if you ask me.  i'm not often on
wobbly ground when it comes to python, but this is pretty specific
stuff that has to be got right across multiple platforms.

tia,
