sub main {
my %opts;
### Get options:
getopts('', \%opts) or die "usage error\n";
my $gifpath = $ARGV[0] || die "missing path to GIF\n";
### Create message:
my $msg = MIME::Lite->new(To => 'me@somewhere.com',
Subject => 'GIF test',
Type => 'multipart/mixed');
### Read data:
open IN, "<$gifpath" or die "open $gifpath: $!\n";
binmode IN;
my @data;
local $_ = '';
while (read(IN, $_, 1024)) {
push @data, $_;
}
close IN;
### Direct path:
if (1) {
my $path = $gifpath;
$msg->attach(Subject => "Read path directly",
Path => $path,
Type => 'image/gif');
}
### Cat (Unix only):
if (1) {
my $path = "cat $gifpath |";
$msg->attach(Subject => "Cat path to pipe, and read that",
Path => $path,
Type => 'image/gif');
}

if (1) {
$msg->attach(Subject => "Read data as array",
Data => \@data,
Type => 'image/gif');
}
### String:
if (1) {
$msg->attach(Subject => "Read data as string",
Data => join('', @data),
Type => 'image/gif');
}
