=head1 NAME

csv_to_db - convert comma-separated-value data into fsdb

=head1 SYNOPSIS

    csv_to_db <source.csv 

=head1 DESCRIPTION

Converts a comma-separated-value data stream to Fsdb format.

The input is CSV-format (I<not> fsdb).
The first row is taken to be the names of the columns.

The output is two-space-separated fsdb.
(Someday more general field separators should be supported.)
Fsdb fields are normalized version of the CSV file:
spaces are converted to single underscores.

=head1 OPTIONS

=over 4

=item B<-F> or B<--fs> or B<--fieldseparator> S

Specify the field (column) separator as C<S>.
See L<dbfilealter> for valid field separators.
Default is S (double space).

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.
