Usage: buildout [options] [assignments] [command [command arguments]]
Options:
-h, --help
Print this message and exit.
-v
Increase the level of verbosity. This option can be used multiple times.
-q
Decrease the level of verbosity. This option can be used multiple times.
-c config_file
Specify the path to the buildout configuration file to be used.
This defaults to the file named "buildout.cfg" in the current
working directory.
-t socket_timeout
Specify the socket timeout in seconds.
-U
Don't read user defaults.
-o
Run in off-line mode. This is equivalent to the assignment
buildout:offline=true.
-O
Run in non-off-line mode. This is equivalent to the assignment
buildout:offline=false. This is the default buildout mode. The
-O option would normally be used to override a true offline
setting in a configuration file.
-n
Run in newest mode. This is equivalent to the assignment
buildout:newest=true. With this setting, which is the default,
buildout will try to find the newest versions of distributions
available that satisfy its requirements.
-N
Run in non-newest mode. This is equivalent to the assignment
buildout:newest=false. With this setting, buildout will not seek
new distributions if installed distributions satisfy it's
requirements.
-D
Debug errors. If an error occurs, then the post-mortem debugger
will be started. This is especially useful for debuging recipe
problems.
-s
Squelch warnings about using an executable with a broken -S
implementation.
Assignments are of the form: section:option=value and are used to
provide configuration options that override those given in the
configuration file. For example, to run the buildout in offline mode,
use buildout:offline=true.
Options and assignments can be interspersed.
Commands:
install [parts]
Install parts. If no command arguments are given, then the parts
definition from the configuration file is used. Otherwise, the
arguments specify the parts to be installed.
Note that the semantics differ depending on whether any parts are
specified. If parts are specified, then only those parts will be
installed. If no parts are specified, then the parts specified by
the buildout parts option will be installed along with all of
their dependencies.
bootstrap
Create a new buildout in the current working directory, copying
the buildout and setuptools eggs and, creating a basic directory
structure and a buildout-local buildout script.
init
Initialize a buildout, creating a buildout.cfg file if it doesn't
exist and then performing the same actions as for the buildout
command.
setup script [setup command and options]
Run a given setup script arranging that setuptools is in the
script's path and and that it has been imported so that
setuptools-provided commands (like bdist_egg) can be used even if
the setup script doesn't import setuptools itself.
The script can be given either as a script path or a path to a
directory containing a setup.py script.
annotate
Display annotated sections. All sections are displayed, sorted
alphabetically. For each section, all key-value pairs are displayed,
sorted alphabetically, along with the origin of the value (file name or
COMPUTED_VALUE, DEFAULT_VALUE, COMMAND_LINE_VALUE).
