 * Advantages over other competitors
 
+There are many competitors of EasyPG such as Mailcrypt, PGG, gpg.el,
+etc.  EasyPG has some advantages over them.

 ** EasyPG avoides potential security flaws of Emacs.

 *** There is no way to clear strings safely.
 
 If Emacs crashed and dumps core, passphrase strings in memory are also
-dumped with the core file.  `read-passwd' function clears passphrase
-strings by `(fillarray string 0)'.  However, it is not perfect.  Emacs
-does compaction of small strings in gc_sweep phase.  If GC happens
-before `fillarray', passphrase strings may be copied elsewhere in
-memory.  So, it is recommended that if you are done with passphrase
-you should clear it manually.  However, PGG and gpg.el enables
-passphrase caching by default.

+dumped within the core file.  `read-passwd' function clears passphrase
+strings by `(fillarray string 0)'.  However, Emacs performs compaction
+in gc_sweep phase.  If GC happens before `fillarray', passphrase
+strings may be moved elsewhere in memory.  It is recommended that as
+soon as you are done with passphrase you should clear it manually.
+However, PGG and gpg.el can keep passphrase strings in cache for a
+while and this behavior is their default!
+
+** GnuPG features are directly accessible from Emacs
+
+Other competitors provide only specific features of GnuPG since they
+still support PGP 2.*, 5.*, 6.*.  As the name indicates, EasyPG is
+inspired by GPGME (GnuPG Made Easy), and the library interface is
+close to GPGME.  With EasyPG you can benefit from a lot of features of
+GnuPG.
