=head1 DESCRIPTION

The B<paia> command line client can be used to access library patron account
information, such as loans, reservations, and fees via the Patrons Account
Information API (PAIA). 

PAIA defines three commands for authentification (PAIA auth) and six commands
to access a patron account (PAIA core). For instance

    paia items [options]

calls the "items" command of PAIA core. Access to PAIA core commands is granted
by access tokens that can be required by the "login" command. By default the
client automatically calls "login" if needed.  Access token, patron identifier
and PAIA server URLs are stored in a session file (C<paia-session.json> by
default) that can be checked with command "session".

Basic options, such as base/core/auth URLs, username, and password can be stored
in a config file (C<paia.json> by default), such as following:

    {
      "base": "http://example.org/paia/",
      "username": "alice",
      "password": "12345"
    }

=head1 COMMANDS

Call C<< paia help <command> >> for help on a specific PAIA command. Note that
PAIA servers do not need to support all PAIA commands.
