Commit 60e586ae authored by jim's avatar jim

Improved intro text and description of setup.

Added documentation of buildout:directory option.

Added support for extending configurations through multiple
configuration files.

Added command-line options to:

- Specify a configuration file

- Override configuration options

Renamed several options to use -s rather than _s.

Multiple configuration files
----------------------------
You can use multiple configuration files. From your main
configuration file, you can include other configuration files in 2
ways:
- Your configuration file can "extend" another configuration file.
Option are read from the other configuration file if they aren't
already defined by your configuration file.
- Your configuration file can be "extended-by" another configuration
file, In this case, the options in the other configuration file
override options in your configuration file.
The configuration files your file extends or is extended by can extend
or be extended by other configuration files. The same file may be
used more than once although, of course, cycles aren't allowed.
To see how this works, we use an example:
>>> write(sample_buildout, 'buildout.cfg',
... """
... [buildout]
... extends = base.cfg
...
... [debug]
... op = buldout
... """)
>>> write(sample_buildout, 'base.cfg',
... """
... [buildout]
... develop = recipes
... parts = debug
...
... [debug]
... recipe = recipes:debug
... op = base
... """)
>>> print system(os.path.join(sample_buildout, 'bin', 'buildout')),
op buldout
recipe recipes:debug
The example is pretty trivial, but the pattern it illustrates is
pretty common. In a more practical example, the base buildout might
represent a product and the extending buildout might be a
customization.
Here is a more eleborate example.
>>> import tempfile
>>> extensions = tempfile.mkdtemp()
>>> write(sample_buildout, 'buildout.cfg',
... """

recipe recipes:debug
There are several things to note about this example:
- We can name multiple files in an extends or extended-by option.
- We can reference files recursively.
- DEFAULT sections only directly affect the configuration file they're
used in, but they can have secondary effects. For example, the name
option showed up in the debug section because it was defined in the
debug sections in several of the input files by virtue of being in
their DEFAULT sections.
- Relative file names are determined relative to the directory
containing the referencing configuration file. The files eb.cfg and
ee.cfg were found in the extensions directory because they were
referenced from a file in that directory.
User defaults
-------------
If the file $HOME/.buildout/defaults.cfg, exists, it is read before
reading the configuration file. ($HOME is the value of the HOME
enviornment variable. The '/' is replaced by the operating system file
delimiter.)
>>> home = tempfile.mkdtemp()
>>> mkdir(home, '.buildout')
>>> write(home, '.buildout', 'default.cfg',

recipe recipes:debug
Command-line usage
------------------
A number of arguments can be given on the buildout command line. The
command usage is::
buildout [-c file] [options] [command [command arguments]]
The -c option can be used to specify a configuration file, rather than
buildout.cfg in the current durectory. Options are of the form::
section_name:option_name=value
for example, as in:
>>> print system(os.path.join(sample_buildout, 'bin', 'buildout')
... + ' debug:op1=foo'),
name ee
op buildout
op1 foo
op2 b1 2
op3 b2 3
op4 b2 4
op5 eb 5
op6 ee 6
op7 7
recipe recipes:debug
Currently, the default and only command is 'install' and it takes a
list of parts to install. if any parts are specified, then only those
parts are installed. To illustrate this, we'll update our
configuration and run the buildout in the usual way:
>>> write(sample_buildout, 'buildout.cfg',

Note that the installed data for debug, d1, and d2 haven't changed,
because we didn't install those parts and that the d1 and d2

We see the output of the debug recipe and that data2 was created. We
