Something like this would work:

C:\counterpartyd>python counterpartyd.py send --from 1Fz5idgemYfsszRMmaQNd2Anvm2JytAoU --to 12J1YFvsWHDCU5HNAWNLNy1Q9nZo8Q4Xgs --quantity 1 --asset XCP
Confirm? (y/N) y
"0783dd6b65303b54b72cbc632f17f6c13e9e9550f2b3fb96270d997cf85a6dce"

Obviously, replace my address w/ yours.

Make sure you already unlocked your bitcoin wallet with walletpassphrase, of course.

Look for the 1 XCP tip in the next few blocks.
