=head1 DESCRIPTION

B<build_ldif.pl> accepts the name of a target folder as an argument. It
then opens that folder and rummages through all the mail files in it, looking
for "Reply-to:" headers (or "From:" headers, where there is no "Reply-to:").
It then prints to STDOUT a file in ldif format containing entries for all of 
the addresses that it finds. It also appends a message into the specified folder containing
all of the addresses in both the B<To:> field of the message header and in an 
LDIF-format attachment.

B<build_ldif.pl> requires B<MIME::Lite>.
