;  File Typing Rules

;

;  This file is used by Pegasus Mail to determine the "attachment type"

;  information for files automatically. It consists of rules that can

;  test a file's extension and any byte or strings in the first 512

;  bytes of the file. Each line contains the complete set of rules for

;  a single type of file, in the following format:

;

;     <file type>,<match type>,<operation>[,<operation>...]

;

;     "file type" is the WinPMail "attachment type" string that

;         should be used if a file matches this rule.

;

;     "match type" is one of the following values:

;         0 : Match is good if any operation succeeds

;         1 : Match is only good if all operations succeed

;

;     "operation" is one or more groups of three parameters in

;     the following format:

;         <opcode>,<offset>,<string>

;             "opcode" is one of the following characters:

;                 X : match the file's extension

;                 B : match the single byte contained in "string"

;                     at offset "offset" in the file

;                 S : match the string contained in "string" starting

;                     at offset "offset" in the file

;                 R : match the string contained in "string" anywhere

;                     in the first 512 bytes of the file

;             "offset" is the offset to start matching in the file. When

;                 "operation" is either X or R, it should be set to 0

;             "string" is the string or byte to match. It can be ASCII

;                 characters, or escapes in the form "\xxx", where "xxx"

;                 is exactly three decimal characters.

;

;   Examples:

;      MS-Word,0,X,0,.DOC

;         - Returns "MS-Word" if the file's extension is ".DOC".
