-Note that we expect this field will eventually be replaced by a proper
-<file>debian/control</file> field understood by <prgn>dpkg</prgn> and
-<tt>&packages-host;</tt>. If you don't want to bother migrating the
-home page from the description to this field, you should probably wait
-until that is available.
- Please make sure that this line matches the regular expression
- <tt>/^ Homepage: [^ ]*$/</tt>,
- as this allows <file>packages.debian.org</file> to parse it correctly.</p>
+Value of this field should be a string identifying unequivocally the
+location of the Version Control System repository used to maintain the
+given package, if available. <tt>*</tt> identify the Version Control
+System; currently the following systems are supported by the package
+tracking system: <tt>arch</tt>, <tt>bzr</tt> (Bazaar), <tt>cvs</tt>,
+<tt>darcs</tt>, <tt>git</tt>, <tt>hg</tt> (Mercurial), <tt>mtn</tt>
+(Monotone), <tt>svn</tt> (Subversion). It is allowed to specify different
+VCS fields for the same package: they will all be shown in the PTS web
+interface.
+ <p>
+The information is meant to be useful for a user knowledgeable in the
+given Version Control System and willing to build the current version of
+a package from the VCS sources. Other uses of this information might
+include automatic building of the latest VCS version of the given
+package. To this end the location pointed to by the field should better
+be version agnostic and point to the main branch (for VCSs supporting
+such a concept). Also, the location pointed to should be accessible to
+the final user; fulfilling this requirement might imply pointing to an
+anonymous access of the repository instead of pointing to an
+SSH-accessible version of the same.
+ <p>
+In the following example, an instance of the field for a Subversion
+repository of the <package>vim</package> package is shown. Note how the
+URL is in the <tt>svn://</tt> scheme (instead of <tt>svn+ssh://</tt>) and
+how it points to the <file>trunk/</file> branch. The use of the
+<tt>Vcs-Browser</tt> and <tt>Homepage</tt> fields described above is
+also shown.
