+### SpendFrom ###
+
+Use the raw transactions API to send coins received on a particular
+address (or addresses).
+
+Depends on `jsonrpc`
+
+Usage:
+
+	spendfrom.py --from=FROMADDRESS1[,FROMADDRESS2] --to=TOADDRESS --amount=amount \
+	             --fee=fee --datadir=/path/to/.bitcoin --testnet --dry_run
+
+With no arguments, outputs a list of amounts associated with addresses.
+
+With arguments, sends coins received by the `FROMADDRESS` addresses to the `TOADDRESS`.
+
+You may explictly specify how much fee to pay (a fee more than 1% of the amount
+will fail,  though, to prevent bitcoin-losing accidents). Spendfrom may fail if
+it thinks the transaction would never be confirmed (if the amount being sent is
+too small, or if the transaction is too many bytes for the fee).
+
+If a change output needs to be created, the change will be sent to the last
+`FROMADDRESS` (if you specify just one `FROMADDRESS`, change will go back to it).
+
+If `--datadir` is not specified, the default datadir is used.
+
+The `--dry_run` option will just create and sign the the transaction and print
+the transaction data (as hexadecimal), instead of broadcasting it.
+
+If the transaction is created and broadcast successfully, a transaction id
+is printed.
+
+If this was a tool for end-users and not programmers, it would have much friendlier
+error-handling.
