* suitable for the format it is being displayed in.
*
* For example, the string: "It's required that you enter a username & password.\n"
* If this were to be displayed as HTML it would be sensible to turn the
* ampersand into '&' and the apostrophe into '&aps;'. However if it were
* going to be used as a string in JavaScript to be displayed in an alert box
* it would be right to leave the string as-is, but c-escape the apostrophe and
* the new line.
*
* For each function there is a define to avoid problems with strings being
* incorrectly specified.
