package Net::Netrc;
-=head1 NAME
-
-Net::Netrc - OO interface to users netrc file
-
-=head1 SYNOPSIS
-
- use Net::Netrc;
-
- $mach = Net::Netrc->lookup('some.machine');
- $login = $mach->login;
- ($login, $password, $account) = $mach->lpa;
-
-=head1 DESCRIPTION
-
-C<Net::Netrc> is a class implementing a simple interface to the .netrc file
-used as by the ftp program.
-
-C<Net::Netrc> also implements security checks just like the ftp program,
-these checks are, first that the .netrc file must be owned by the user and
-second the ownership permissions should be such that only the owner has
-read and write access. If these conditions are not met then a warning is
-output and the .netrc file is not read.
-
-=head1 THE .netrc FILE
-
-The .netrc file contains login and initialization information used by the
-auto-login process. It resides in the user's home directory. The following
-tokens are recognized; they may be separated by spaces, tabs, or new-lines:
-
-=over 4
-
-=item machine name
-
-Identify a remote machine name. The auto-login process searches
-the .netrc file for a machine token that matches the remote machine
-specified. Once a match is made, the subsequent .netrc tokens
-are processed, stopping when the end of file is reached or an-
-other machine or a default token is encountered.
-
-=item default
-
-This is the same as machine name except that default matches
-any name. There can be only one default token, and it must be
-after all machine tokens. This is normally used as:
-
- default login anonymous password user@site
-
-thereby giving the user automatic anonymous login to machines
-not specified in .netrc.
-
-=item login name
-
-Identify a user on the remote machine. If this token is present,
-the auto-login process will initiate a login using the
-specified name.
-
-=item password string
-
-Supply a password. If this token is present, the auto-login
-process will supply the specified string if the remote server
-requires a password as part of the login process.
-
-=item account string
-
-Supply an additional account password. If this token is present,
-the auto-login process will supply the specified string
-if the remote server requires an additional account password.
-
-=item macdef name
-
-Define a macro. C<Net::Netrc> only parses this field to be compatible
-with I<ftp>.
-
-=back
-
-=head1 CONSTRUCTOR
-
-The constructor for a C<Net::Netrc> object is not called new as it does not
-really create a new object. But instead is called C<lookup> as this is
-essentially what it deos.
-
-=over 4
-
-=item lookup ( MACHINE [, LOGIN ])
-
-Lookup and return a reference to the entry for C<MACHINE>. If C<LOGIN> is given
-then the entry returned will have the given login. If C<LOGIN> is not given then
-the first entry in the .netrc file for C<MACHINE> will be returned.
-
-If a matching entry cannot be found, and a default entry exists, then a
-reference to the default entry is returned.
-
-=back
-
-=head1 METHODS
-
-=over 4
-
-=item login ()
-
-Return the login id for the netrc entry
-
-=item password ()
-
-Return the password for the netrc entry
-
-=item account ()
-
-Return the account information for the netrc entry
-
-=item lpa ()
-
-Return a list of login, password and account information fir the netrc entry
