The following characters have a special meaning in a formatting string:\r\n\r\n\
?<function>(<arguments>)\r\n\
This will parse the function given the arguments, the result will be parsed again. Example: Today is ?cdate(yyyy/MM/dd).\r\n\r\n\
!<function>(<arguments>)\r\n\
This will parse the function given the arguments, the result will not be parsed again. Example: Message waiting: !message(,first,rcvd,unread).\r\n\r\n\
%<field>%\r\n\
This will parse the given field. Example: I installed Miranda at: %mirandapath%.\r\n\r\n\
`<string>`\r\n\
This will not parse the given string, any function, field or special character in the string will shown in the result without being translated. Example: Use `%mirandapath%` to show the installation path.\r\n\r\n\
#<comment>\r\n\
This will add a comment in the formatting string. Everything from the # character to the end of the line will be removed. Example: %dbprofile% #this is a useless comment.\r\n\r\n\r\n\
--- Contacts ---\r\n\r\n\
Whenever a functions requires a contact as an argument, you can specify it in two ways:\r\n\r\n\
(1) Using a unique ID (UIN for ICQ, email for MSN) or, a protocol ID followed by a unique ID in the form <PROTOID:UNIQUEID>, for example <MSN:miranda@hotmail.com> or <ICQ:123456789>.\r\n\r\n\
(2) Using the contact function:\r\n\
?contact(x,y)\r\n\
A contact will be searched which will have value x for its property y, y can be one of the following:\r\n\
first, last, nick, email, ID or display\r\n\r\n\
For example: ?contact(miranda@hotmail.com,email) or ?contact(Miranda,nick). \
The contact function will return either a unique contact according to the arguments or nothing if none or multiple contacts exists with the given property.")
