=head1 NAME

cpandb - interface to C<CPAN::SQLite>

=head1 DESCRIPTION

This script is an interface to the routines of
L<CPAN::SQLite> for setting up, maintaining and
searching a C<DBD::SQLite> database
of CPAN. Available options can be grouped into
three categories.

=head2 Common options

These are options which are common to both setting up
and maintaining the database or performing queries on it.
These are

=over 3

=item * C<--CPAN  '/path/to/CPAN'>

This specifies the path to where the index files are
to be stored. This could be a local CPAN mirror,
defined here by the presence of a F<MIRRORED.BY> file beneath
this directory, or a local directory in which to store
these files from a remote CPAN mirror. In the latter case,
the index files are fetched from a remote CPAN mirror,
using the same list that C<CPAN.pm> uses, if this is
configured, and are updated if they are more than one
day old.

If the C<CPAN> option is not given, it will default
to C<cpan_home> of L<CPAN>, if this is configured,
with the sources being found under C<keep_source_where>.
A fatal error results if such a directory isn't found.
Updates to these index files are assumed here to be
handled by C<CPAN.pm>.

=item * C<--db_name  'cpan-sqlite'>

This is the name of the database that C<DBD::SQLite>
will use. If not given, this defaults to C<cpandb-sqlite>.

=item * C<--db_dir  '/path/to/db/dir'>

This specifies the path to where the database file is
found. If not given, it defaults to the
C<cpan_home> directory of C<CPAN.pm>, if present, or to
the directory in which the script was invoked.

=back

=head2 Indexing options

These are options which are used for setting up and
maintaining the database. These include

=over 3

=item * C<--setup>

This specifies that the database is to be created and
populated from the CPAN indices; any exisiting database
will be overwritten.

=item * C<--update>

This is used to update an exisiting database,
which must have first been created with the C<setup>
option.

=item * C<--reindex 'dist_name'>

This specifies that the CPAN distribution C<dist_name>
is to be reindexed.

=back

=head2 Querying options

These options are used to query the database. Available
options are

=over 3

=item * C<--module Mod::Name>

This provides information on the specified module name.

=item * C<--dist Dist-Name>

This provides information on the specified distribution name.

=item * C<--cpanid CPANID>

This provides information on the specified CPAN author id

=back

All search terms are assumed to be exact matches in a
case-insensitive manner.

=head1 SEE ALSO
