Parse mailcap files as specified in RFC 1524 - A User Agent
Configuration Mechanism For Multimedia Mail Format Information. In
the description below $type refers to the MIME type as specified in
the Content-Type header of mail or HTTP messages. Examples of
types are:
$mcap = new Mail::Cap;
$mcap = new Mail::Cap "/mydir/mailcap";
$mcap = new Mail::Cap filename => "/mydir/mailcap";
$mcap = new Mail::Cap take => 'ALL';
$mcap = Mail::Cap->new(take => 'ALL');
Create and initialize a new Mail::Cap object. If you give it an
argument it will try to parse the specified file. Without any
arguments it will search for the mailcap file using the standard
mailcap path, or the MAILCAPS environment variable if it is defined.
Include all mailcap files you can find. By default, only the first
file is parsed, however the RFC tells us to include ALL. To maintain
backwards compatibility, the default only takes the FIRST.
These methods invoke a suitable progam presenting or manipulating the
media object in the specified file. They all return 1if a command
was found, and 0 otherwise. You might test $? for the outcome
of the command.
These methods return a string that is suitable for feeding to system()
in order to invoke a suitable progam presenting or manipulating the
media object in the specified file. It will return undefif no
suitable specification exists.
These methods return the corresponding mailcap field for the type.
These methods should be more convenient to use than the field() method
for the same fields.
