+VERSION
     a string describing what version of the code the current checkout is
-    based on. The exact format of this string depends on the version
-    control system in use, but it tries to identify the revision used as
-    close as possible (using the svn revision number or hg/git hash).
-    This also includes an indication of whether the checkout was
-    modified and which branch was checked out. This value is not
+    based on.
+    This also includes the commit date, an indication of whether the checkout
+    was modified and which branch was checked out. This value is not
     guaranteed to be sortable, but is mainly meant for identifying the
     revision and user display.
 
     If no revision identifier could be found, this is left empty.
-REV_NR
-    the revision number of the svn revision this checkout is based on.
-    This can be used to determine which functionality is present in this
-    checkout. For trunk svn checkouts and hg/git branches based upon it,
-    this number should be accurate. For svn branch checkouts, this
-    number is mostly meaningless, at least when comparing with the
-    REV_NR from other branches or trunk.
+ISODATE
+    the commit date of the revision this checkout is based on.
+    The commit date may differ from the author date.
+    This can be used to decide upon the age of the source.
 
-    This number should be sortable. Within a given branch or trunk, a
-    higher number means a newer version. However, when using git or hg,
-    this number will not increase on new commits.
-
-    If no revision number could be found, this is left empty.
+    If no timestamp could be found, this is left empty.
 MODIFIED
     Whether (the src directory of) this checkout is modified or not. A
     value of 0 means not modified, a value of 2 means it was modified.
-    Modification is determined in relation to the commit identified by
-    REV, so not in relation to the svn revision identified by REV_NR.
 
     A value of 1 means that the modified status is unknown, because this
-    is not an svn/git/hg checkout for example.
+    is not an git checkout for example.
 
-CLEAN_REV
-    the same as REV but without branch name
+HASH
+    the git revision hash
