=head1 NAME
Chirpy::Util::IniFile - Load from and save to an INI file
=head1 SYNOPSIS
$inifile = new Chirpy::Util::IniFile('/path/to/inifile.ini');
$value = $inifile->get($section, $name);
$inifile->set($section, $name, $value);
undef $inifile;
=head1 NOTE
The C<undef $inifile;> in the above example is not necessary to trigger an
update of the file's contents. The file is updated as soon as the object goes
out of scope (but only if the C<set()> function has been called).
