=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.
