# NOTE TO LAUNCHPAD DEVELOPERS: This is a bootstrapping file from the
16
# zc.buildout project, which we have hacked slightly: look for the string

Simply run this script in a directory containing a buildout.cfg.
22
17
The script accepts buildout command-line options, so you can
23
18
use the -c option to specify an alternate configuration file.

This script recognizes the following options itself. The first option it
37
encounters that is not one of these will cause the script to stop parsing
38
options and pass the rest on to buildout. Therefore, if you want to use
39
any of the following options *and* buildout command-line options like
40
-c, first use the following options, and then use the buildout options.
41
42
Options:
43
--version=ZC_BUILDOUT_VERSION
44
Specify a version number of the zc.buildout to use
45
--ez_setup-source=URL_OR_FILE
46
Specify a URL or file location for the ez_setup file.
47
Defaults to
48
%(--ez_setup-source)s
49
--download-base=URL_OR_DIRECTORY
50
Specify a URL or directory for downloading setuptools and
51
zc.buildout. Defaults to PyPI.
52
--eggs=DIRECTORY
53
Specify a directory for storing eggs. Defaults to a temporary
54
directory that is deleted when the bootstrap script completes.
55
56
By using --ez_setup-source and --download-base to point to local resources,
57
you can keep this script from going over the network.
