-Useage:
-    bb64 BASE64COMMAND      Decodes the base64 encoded command, and runs it
-    bb64 -i BASE64COMMAND   Decodes the base64 encoded command, and prints to the screen

+Usage:
+    bb64 BASE64COMMAND          Decodes and runs the command
+    bb64 -[i|d] BASE64COMMAND   Displays the decoded command
+    bb64 -e COMMAND             Encodes the command and prints the result

 # Implementation Notes
@@ -27,11 +26,9 @@ bb64 runs the command by replacing the current process, so it ensures that tty,
 variables etc are all identical for the run command. It works with interactive commands, like
 nano or ssh.
 
-The command is run as:
-    `bash -c COMMAND`
+bb64 supports bash scripts, as the command is run as:
+    `bash -c 'COMMAND'`
 Where COMMAND is passed to bash as a single argument.
 
 If the command is run, the return value is the return value of the command.
 If it isn't run, bb64 returns -1.
