+0.2.2   Enhanded --edit-key a little, it's now possible to

+	Added new option -v (the previous -v has moved to
+	--version only) for verbose. Currently only supported
+	by --list-keys. In this mode more details will be

+	Removed options -P and -S, replaced by -K (long:

+	is now determined automatically as well as the

+
+	Made libpcp threadsafe by removing all global vars
+	and putting that stuff into the new PCP Context
+	class (ptx.h), which now holds errors and key hashes.
+
+	Use 64bit integers for time values in exported
+	keys (we use 64 bit internaly already), to be
+	year 2038 safe.
+
+	Added a new file type (PCP_ASYM_CIPHER_SIG) which
+	marks encrypted+signed files. This is incompatible
+	to pbp, but it doesn't support that feature anyway.
+	To decrypt encrypted+signed files the option -c
+	is therefore no more required, since pcp2 can now
+	determine the file mode itself.
