.Vb 1
\&    use Text::DHCPLeases;
\&
\&    my $leases = Text::DHCPLeases\->new("/etc/dhcpd.leases");
\&
\&    foreach my $obj ( $leases\->get_objects ){

.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module provides an object-oriented interface to \s-1ISC DHCPD\s0 leases files.  
The goal is to objectify all declarations, as defined by the \s-1ISC\s0 dhcpd package man pages.
.PP
This interface is useful for analyzing, reporting, converting lease files, 
or as a tool for other applications that need to import dhcpd lease data structures.

\&  Arguments:
\&    Hash with the following keys:
\&    file  \-  Leases file path
\&  Returns:
\&    Text::DHCPLeases object
\&  Examples:
\&    Text::DHCPLeases\->new(file=>"/etc/dhcpd.leases");

\&  Arguments:
\&    Object attributes to match (optional)
\&  Returns:
\&    Array of Text::DHCPLeases::Lease objects, 
\&    or iterator depending on context.  
\&  Examples:
\&    my $it = $leases\->get_objects(ip_address=>\*(Aq192.168.0.1\*(Aq);

.SH "BUGS AND LIMITATIONS"
.IX Header "BUGS AND LIMITATIONS"
Correct parsing of leases files depends on changes made to the format of
said files by the authors of the \s-1ISC DHCPD\s0 package.  This module was tested
against leases files generated by \s-1ISC DHCPD\s0 version 3.1.0.  In addition, I
do not have access to leases file with all possible declarations and statements,
so parsing could be broken in some circumstances.  Patches are welcome.

No bugs have been reported.
