And I usually don't need it to be copied, since on the production server
I will install these package by hand, from a Mercurial working copy.

But the idea was to copy all required packages to a common directory, so
that I can create a tar archive from this directory and use it on the
And to have this done automatically, without having to build each
The needed packages are usually already on sys.path, since they have
been installed the first time I executed "python setup.py develop" for
my package, on my development machine.
The trivial solution is of course to not use "develop" command, and to
build a normal egg.
I would like that setuptools will just copy the .egg-info file, *making
sure* to use a relative path instead of an absolute path.
As an example, using virtualenv I have this layout:
`env` is the virtual environment.
Inside the `hg` directory I have clones of the packages required by A
and that are still under heavy development; these packages are installed
using "develop" command.
Inside the `deps` directory, I have all the eggs required by A and B
I copy all required eggs in this directory, using `-maxd` options, on my
Then I create a tar archive, and, on the production server, I recreate
The virtual environment is recreated each time, I do not use the
- --relocatable option.
If `-maxd` will make the B.egg-info file relative, then all I need to do
is to `python setup.py develop` inside A directory, and B package should
be correctly available.
Is this possible?
Thanks and sorry for the long message
