{- |
Creates a new file attribute matcher, which matches attributes
against a given string. @/GFileAttributeMatchers/@ are reference
counted structures, and are created with a reference count of 1. If
the number of references falls to 0, the 'GI.Gio.Structs.FileAttributeMatcher.FileAttributeMatcher' is
automatically destroyed.

The /@attribute@/ string should be formatted with specific keys separated
from namespaces with a double colon. Several \"namespace::key\" strings may be
concatenated with a single comma (e.g. \"standard::type,standard::is-hidden\").
The wildcard \"*\" may be used to match all keys and namespaces, or
\"namespace::*\" will match all keys in a given namespace.

== Examples of file attribute matcher strings and results


* @\"*\"@: matches all attributes.
* @\"standard::is-hidden\"@: matches only the key is-hidden in the
standard namespace.
* @\"standard::type,unix::*\"@: matches the type key in the standard
namespace and all keys in the unix namespace.
