+PLIST_VARS introduced [jlam 20080413]
+       PLIST_VARS is a simpler way to do conditional PLIST entries.
+       The old method of doing e.g. PLIST_SUBST+= FOO="@comment " can
+       now be done by unconditionally setting PLIST_VARS+=foo and
+       conditionally setting PLIST.foo=yes. This will result in substitution
+       of ${PLIST.foo} in the PLIST with either "" or "@comment ".

 SKIP_PORTABILITY_CHECK is obsolete [rillig 20080220]
        After being deprecated for about 16 months, this early misdesign
        has finally been obsoleted and removed from pkgsrc.
