Update of /cvs-repository/Packages/zpkgtools/doc
In directory cvs.zope.org:/tmp/cvs-serv6741
document zpkg configuration
=== Added File Packages/zpkgtools/doc/zpkg.txt ===
Overview and the Command Line
Configuration of **zpkg** is required since **zpkg** always refers to
a `resource map` to provide information about the resource its
packaging. Regardless of the availability of an appropriate checkout,
**zpkg** always uses the resource map to locate the components it's
adding to the release.
The **zpkg** command provides some command line options to control
configuration, and a very simple configuration file to allow
configurations to be saved.
The following command line options are provided:
-C FILE, --configuraion=FILE
Load the configuration file FILE instead of the default
configuration file. FILE must exist.
Don't load any configuration file, not even the default.
-m MAP, --resource-map=MAP
Load the resource map MAP before loading any map files identified in
the configuration file. Maps identified using **-m** take
precedence over any identified inthe configuration file.
If neither **-C** nor **-f** is specified on the command line, a
default configuration file is loaded if it exists. This is
`~/.zpkg/zpkg.conf` on Unix and `~/zpkg/zpkg.conf` on Windows (note
that there's no dot in the directory name for Windows). The directory
containing the default configuration file can be used to store
Configuration File Format
The configuration files used by **zpkg** use a subset of the
`ZConfig`_ configuration language.
Blank lines and comments (lines that start with ``#`` as the first
non-blank character) are ignored.
The only key currently defined for the configuration file is
``resource-map``. The value for this key is a path or URL (including
``cvs:`` URLs) for a file that defines the map. Relative paths are
interpreted as relative to the directory containing the configuration
file. The ``resource-map`` key may be given any number of times;
entries in the first named map take precedence over entries of the
same name in later maps.
For example, if the configuration file `/home/fdrake/zpkg.conf`
**zpkg** will first load the maps in the order:
A `resource map` is a mapping of typed resource names to URLs. The
URLs will most often be ``cvs:`` or ``repository:`` URLs, but do not
have to be (well, they do for now, but presumably not forever).
Resources are identified by strings of the form:
[ `type` ":" ] `name`
The optional `type` defaults to ``package``.
The only types known to **zpkg** are ``package`` and ``collection``.
The `name` portion may be used to represent different resources of
different types. For example, ``collection:ZConfig`` and
``package:ZConfig`` represent two different resources.
A file representing a resource map is a simple two-column table with
the fields separated by writespace. Blank lines and comments (lines
that start with ``#`` as the first non-blank character) are ignored.
The first field is the name of a resource, and the second field is the
URL by which it can be accessed.
Resource maps which have CVS locations of their own can contain
``repository:`` URLs; the ``cvs:`` URL of the directory containing the
map itself is used as the base for resolving ``repository:`` URLs.
