Magic Flags

You can use either constants or keyword list as magic flags. I.e.,

(magic-open (logxor +magic-mime-type+ +magic-symlink+))

is equivalent to

(magic-open '(:mime-type :symlink))

The constant name and keyword name of a flag are based on its C name. See the following table for the pattern:

C name	Lisp constant	Lisp keyword
`MAGIC_NONE`	`+MAGIC-NONE+`	`:NONE`

All constant names are exported.
