+Create an ECDSA signature on the P-384 curve using the SHA-384 hash of data from
+stdin. The key used for the signature is the secp384r1Encoded key used in pykey
+and pycert.
+
+The certificates for the content signature tests make use of this program.
+You can use pysign.py like this:
+
+cat test.txt | python pysign.py > test.txt.signature
