-      <title>Subversion's Features</title>
-  
-      <para>When discussing the features that Subversion brings to the
-        version control table, it is often helpful to speak of them in
-        terms of how they improve upon CVS's design.  If you're not
-        familiar with CVS, you may not understand all of these features.
-        And if you're not familiar with version control at all, your
-        eyes may glaze over unless you first read <xref
-        linkend="svn.basic"/>, in which we provide a gentle introduction
-        to version control.</para>
-  
-      <para>Subversion provides:</para>

-      <variablelist>
-        <varlistentry>
-          <term>Directory versioning</term>
-          <listitem>
-            <para>CVS tracks only the history of individual files, but
-              Subversion implements a <quote>virtual</quote> versioned
-              filesystem that tracks changes to whole directory trees
-              over time.  Files <emphasis>and</emphasis> directories are
-              versioned.</para>
-          </listitem>
-        </varlistentry>
-  
-        <varlistentry>
-          <term>True version history</term>
-          <listitem>
-            <para>Since CVS is limited to file versioning, operations
-              such as copies and renames—which might happen to
-              files, but which are really changes to the contents of
-              some containing directory—aren't supported in CVS.
-              Additionally, in CVS you cannot replace a versioned file
-              with some new thing of the same name without the new item
-              inheriting the history of the old—perhaps completely
-              unrelated—file.  With Subversion, you can add,
-              delete, copy, and rename both files and directories.  And
-              every newly added file begins with a fresh, clean
-              history all its own.</para>
-          </listitem>
-        </varlistentry>
-  
-        <varlistentry>
-          <term>Atomic commits</term>
-          <listitem>
-            <para>A collection of modifications either goes into the
-              repository completely or not at all.  This allows
-              developers to construct and commit changes as logical
-              chunks and prevents problems that can occur when only a
-              portion of a set of changes is successfully sent to the
-              repository.</para>
-          </listitem>

-  
-        <varlistentry>
-          <term>Versioned metadata</term>
-          <listitem>
-            <para>Each file and directory has a set of
-              properties—keys and their values—associated
-              with it.  You can create and store any arbitrary key/value
-              pairs you wish.  Properties are versioned over time, just
-              like file contents.</para>

-          <term>Choice of network layers</term>
-          <listitem>
-            <para>Subversion has an abstracted notion of repository
-              access, making it easy for people to implement new network
-              mechanisms.  Subversion can plug into the Apache HTTP
-              Server as an extension module.  This gives Subversion a
-              big advantage in stability and interoperability, and
-              instant access to existing features provided by that
-              server—authentication, authorization, wire
-              compression, and so on.  A more lightweight, standalone
-              Subversion server process is also available.  This server
-              speaks a custom protocol that can be easily tunneled via
-              SSH.</para>

-          <term>Consistent data handling</term>
-          <listitem>
-            <para>Subversion expresses file differences using a binary
-              differencing algorithm, which works identically on both
-              text (human-readable) and binary (human-unreadable) files.
-              Both types of files are stored equally compressed in the
-              repository, and differences are transmitted in both
-              directions across the network.</para>

-          <term>Efficient branching and tagging</term>
-          <listitem>
-            <para>The cost of branching and tagging need not be
-              proportional to the project size.  Subversion creates
-              branches and tags by simply copying the project, using a
-              mechanism similar to a hard link.  Thus these operations
-              take only a very small, constant amount of time.

-          <listitem>
-            <para>Subversion has no historical baggage; it is
-              implemented as a collection of shared C libraries with
-              well-defined APIs.  This makes Subversion extremely
-              maintainable and usable by other applications and
-              languages.</para>
