=head1 NAME

dbformmail - write a shell script that will send e-mail to many people

=head1 SYNOPSIS

dbformmail [-m MECHANISM] format_file.txt

=head1 DESCRIPTION

Read a ``form mail'' message from the file FORMAT_FILE.TXT,
filling in underscore-preceded column-names with data.
Output a shell script which will send each message through some
mail transport MECHANISM.

Do not use this program for evil or I will have to come over
and have words with you.

Note that this program does NOT actually SEND the mail. 
It writes a shell script that will send the mail for you.
I recommend you save it to a file, check it (one last time!),
then run it with sh.

Unlike most Fsdb programs, this program does I<not> output a FSDB file.

=head1 OPTIONS

=over 4

=item B<-m MECHANISM>

Select the mail-sending mechanism: Mail, sendmail, mh.
Defaults to "Mail".

Mail uses a Berkeley-style /usr/bin/Mail.
Sendmail invokes /usr/bin/sendmail.
Mh writes messages into the current directory, treating it
as an mh-style mailbox (one message per file, with filesnames as sequential
integrates).

begin_standard_fsdb_options

This module also supports the standard fsdb options:

=over 4

=item B<-d>

Enable debugging output.

=item B<-i> or B<--input> InputSource

Read from InputSource, typically a file name, or C<-> for standard input,
or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue objects.

=item B<-o> or B<--output> OutputDestination

Write to OutputDestination, typically a file name, or C<-> for standard output,
or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue objects.

=item B<--autorun> or B<--noautorun>

By default, programs process automatically,
but Fsdb::Filter objects in Perl do not run until you invoke
the run() method.
The C<--(no)autorun> option controls that behavior within Perl.

=item B<--help>

Show help.

=item B<--man>

Show full manual.
