Be default, Eclipse uses a single configuration for a given installation. The
configuration information is saved in the platform.xml file found in the
\configuration\org.eclipse.update dirctory. Them primary content in the
configuration is a list install sites. An install site is a location on the file
system where an eclipse directory tree. with feature and plugins directories, can be found.
The configuration identifies what install sites are accessible, lists the features that
exist in each site, and determines what features are available and active when Eclipse is started.
The platform:/base/ site is a reference to the eclipse directory structure from which the eclipse.exe

was started.

The default configuration is used when Eclipse is launched and applies to
any workspace that might be accessed. The -configurationstartup parameter can
be used to identify an alternnative configuration.

A configuration is a list of install sites and the features found in each of these install sites.
An install site is a location that contains features and plug-ins that can be included in the
configuration. The Update Manager processes the content of the features and plugins directiries of

the install site; if the content is valid, it can be included in configuration.

platform.xml文件的部分内容：

<?xml version="1.0" encoding="UTF-8"?>
<config date="1350027346671" transient="false" version="3.0">
<site enabled="true" policy="USER-EXCLUDE" updateable="true" url="platform:/base/">
<feature id="org.eclipse.wst.xml_ui.feature" plugin-identifier="org.eclipse.wst.xml.ui" url="features/org.eclipse.wst.xml_ui.feature_3.3.1.v201108102009-7H7EFZ3DxumTlaI6nheRdHo2p1KaDIL1Uz-S3PL/" version="3.3.1.v201108102009-7H7EFZ3DxumTlaI6nheRdHo2p1KaDIL1Uz-S3PL">
</feature>
<feature id="org.eclipse.equinox.p2.core.feature" url="features/org.eclipse.equinox.p2.core.feature_1.0.1.R37x_v20110906-8290FZ3FUqIcLqkVkEaTdn_14C7G/" version="1.0.1.R37x_v20110906-8290FZ3FUqIcLqkVkEaTdn_14C7G">
</feature>

</site>
</config>

说白了，configuration的目的就是用来指定Eclipse启动时会加载哪些plugins，会使用哪些branding，会使用哪些参数等。
