-This requires pcsc-lite and openct.
+This requires either pcsc-lite or openct (see below for details).

+Since version 0.12.0, only one reader subsystem can be used and compiled
+in at the same time.  The PCSC-LITE subsystem is used by default and it is
+suitable for most smartcards (it requires pcsc-lite).  If you need the 
+OPENCT subsystem instead, you have to pass "OPENCT=1" to the script when
+building and have openct installed.
