Set Parameters
	This window lets you set individual parameters on the
Content-Type: field of the resulting message. This field has strict
syntax which must be observed if you wish to make changes. If you have
no idea what you might change, please select Cancel. This is
considered an advanced option, and your message may end up being
unreadable by the recipient(s) if not set correctly.

	You may also use this to create or edit a parameter entry for
message attachments. To use it in this mode, you must first select an
attachment. If no attachment is selected, the current text message
will be used.

	A typical parameter you may wish to set is CHARSET to use
other than US-ASCII as the default character set; such as the
ISO-8859-1 character set or other ISO latin derivatives. This
particular parameter is also settable via your personal preferences
for all outgoing messages.  Other settings may be defined in a
particular context, such as attachments of type message/external-body,
which will have parameters set to indicate the location of the
external file.

	The syntax you must use is:

token=value token2=value2 [etc...]

	Examples:

CHARSET="ISO-8859-1"

ACCESS-TYPE="ANON-FTP" SITE="podunk.edu" DIRECTORY="/pub" NAME="foobar.txt"

	The first token must start at the first character. There is no
white space between the token, the "=" sign and the value. If the
value contains spaces or other special characters, (such as "=") it
MUST be surrounded in double quotes. Otherwise quotes are optional,
but are considered a good idea if you don't want to be concerned with
finding out what is or isn't a special character. Leave one (and only
one) space between subsequent parameters. The internal parser which
generates this field from your input is very simple and not designed
to handle all possible error conditions.
