=head1 NAME

lr_environment - Export Lire configuration in shell script form

=head1 SYNOPSIS 

eval `B<lr_environment>`

=head1 DESCRIPTION

The B<lr_environment> command is used to import the Lire configuration
in Lire shell scripts.

All of Lire configuration variables will be written in a format that
can be evaled by the shell.

Shell scripts don't usually have to use that command, since it is done
by the F<defaults> file sourced by each command.

The old names used by when the configuration was done in shell script
are also exported by this script for backward compatibility.
