=head1 NAME

sqlt-dumper - create a dumper script from a schema

=head1 SYNOPSIS

  sqlt-dumper -d Oracle [options] schema.sql > dumper.pl

  ./dumper.pl > data.sql

  Options:

    -h|--help         Show help and exit
    --skip=t1[,t2]    Skip tables in comma-separated list
    --skiplike=regex  Skip tables matching the regular expression
    -u|--user         Database username
    -p|--password     Database password
    --dsn             DSN for DBI

=head1 DESCRIPTION

This script uses SQL::Translator to parse the SQL schema and create a
Perl script that can connect to the database and dump the data as
INSERT statements (a la mysqldump) or MySQL's LOAD FILE syntax.  You may
specify tables to "skip" (also using a "skiplike" regular expression)
and the generated dumper script will not have those tables.  However,
these will also be options in the generated dumper, so you can wait to
specify these options when you dump your database.  The database
username, password, and DSN can be hardcoded into the generated
script, or part of the DSN can be intuited from the "database"
argument.
