And if you're using Perl on a Windows OS, as an alternative to Config::IniFiles I recommend that you look into Dave Roth's really useful Win32::AdminMisc module. It includes a ReadINI (and a WriteINI) function that "understands" section dividers, and ignores lines commented out with semi-colons. There's online documentation at http://www.roth.net/perl/adminmisc/, but here's an example of how it could be used:

  foreach my $section (Win32::AdminMisc::ReadINI
             ('some.ini', '', '')) {
    foreach my $key (Win32::AdminMisc::ReadINI
               ('some.ini', $section, '')) {
       my $value = Win32::AdminMisc::ReadINI
                              ('some.ini', $section, $key);
    }
  }

(Note: if you want to use AdminMisc, either use PPM (if you're using ActiveState), or else use the links at Roth's site. It's on CPAN but http://search.cpan.org for some reason doesn't return a match.)

Finally, in the book Data Munging in Perl (written by davorg), there's a longish discussion about using the high-powered Parse::RecDescent module for parsing INI files.
