                 export and use to determine revision number
+
+    The subdir parameter is there to cope with the kdepim enterprise
+    tags.  The URL for a tag is of the form
+    .../tags/kdepim/enterprise4.0.<date>.<rev> .  Each such tag has
+    subdirectories for kdepim, kdelibs, etc.  The url and pattern are
+    used to match the URL for the tag, and the subdir is used to select
+    which part of the tag is meant.
+
+    The subdir also determines which SVN directory's revision number is
+    used.  Normally, just appending the subdir to the tag URL would be
+    enough for this, but the situation is more complex for
+    kdebase_workspace and kdebase_runtime, whose code comes from
+    different subdirectories of the kdebase-4.X-branch subdirectory (for
+    enterprise4 tags).  Here the revision number must be taken from
+    kdebase-4.X-branch, but the URL to use when exporting the sources,
+    must refer to e.g. kdebase-4.1-branch/kdebase_workspace.  To achieve
+    that, subdir may contain slashes to indicate subdirectories of
+    subdirectories, but only the first part of subdir (up to the first
+    slash) is used when determining the revision number.
