=head1 NAME

maemian - Maemo package checker

=head1

Maemian is the maemo version of lintian - a policy checker designed to
assure the quality of a package uploaded into the maemo.org repositories.
The goal of maemian is to improve quality by checking that the maemo
packaging policy is followed. In order to do that it reads files in the
uploaded deb. Currently maemian only looks at the .dsc file and tries to
ascertain who uploaded it, and if they used the correct email address.

=head1 EXAMPLE

maemian -i file.dsc

use strict;
use warnings;
use Getopt::Long;
use Carp;

unshift @INC, "/home/jeremiah/maemian/lib";
require Maemian::Output;
my $lintout = new Maemian::Output;

# --- Command line options
my $inputfile;             # --- A file passed to maemian
GetOptions ("inputfile|i=s" => \$inputfile);

sub file_tests {
  use File::Basename;
  my $path = shift;
  if (-r $path) {
    my ($filename, $dirs) = fileparse($path);
    # --- maemo is a trademarked term
    if ($filename =~ /maemo/) {
      print "W: Any use of the word \"maemo\" is subject to trademark.\n";
    }
    # --- Open file into an array
    open my $file, '<', $path or die "Cannot open file: $!\n";
    my @lines = <$file>;
    close $file;

    my ($field, $maintainer) = map { split /: / } grep /Maintainer/, @lines;
    chomp($maintainer);
    if ($maintainer =~ /(ubuntu|debian)/i) {
