=head1 NAME

dac.pl - Creating "dac" Database File from "dis" Source Files

=head1 SYNOPSIS

  perl path/to/dac.pl [--input-db-file-name=input.dac] \
                      --output-file-name=out.dac [options...] \
                      input.dis
  perl path/to/dac.pl --help

=head1 DESCRIPTION

This script, C<dac.pl>, compiles "dis" source files into "dac"
database file.  The generated database file can be used
in turn to generate Perl module file, for example, by another
script C<dac2pm.pl> or can be used to create larger database
by specifying its file name as the C<--input-db-file-name>
argument of another C<dac.pl> execution.

This script is part of manakai.

=head1 OPTIONS

=over 4

=item I<input.dis> (Required)

The unnamed option specifies a file name path of the source "dis" file
from which a database is created.  This option is required.

=item C<--input-db-file-name=I<file-name>> (Default: none)

A file path of the base database.  This option is optional; if this
option is specified, the database file is loaded first
and then I<input.dis> file is loaded in the context of it.
Otherwise, a new database is created.

=back

L<lib/Message/Util/DIS.dis> - The actual implementation
of the "dis" interpretation.

564			=head1 NAME
565
566			dac.pl - Creating "dac" Database File from "dis" Source Files
567
568			=head1 SYNOPSIS
569
570			perl path/to/dac.pl [--input-db-file-name=input.dac] \
571			--output-file-name=out.dac [options...] \
572			input.dis
573			perl path/to/dac.pl --help
574
575			=head1 DESCRIPTION
576
577			This script, C<dac.pl>, compiles "dis" source files into "dac"
578			database file. The generated database file can be used
579			in turn to generate Perl module file, for example, by another
580			script C<dac2pm.pl> or can be used to create larger database
581			by specifying its file name as the C<--input-db-file-name>
582			argument of another C<dac.pl> execution.
583
584			This script is part of manakai.
585
586			=head1 OPTIONS
587
588			=over 4
589
590			=item I<input.dis> (Required)
591
592			The unnamed option specifies a file name path of the source "dis" file
593			from which a database is created. This option is required.
594
595			=item C<--input-db-file-name=I<file-name>> (Default: none)
596
597			A file path of the base database. This option is optional; if this
598			option is specified, the database file is loaded first
599			and then I<input.dis> file is loaded in the context of it.
600			Otherwise, a new database is created.
