=head1 NAME

paia - Patrons Account Information API command line client 

=head1 VERSION

version 0.27


    paia login --base http://example.org/paia/ -u alice -p 12345
    paia patron
    paia items

Run C<paia help> or C<perldoc paia> for more commands and options.


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"


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

=head2 PAIA auth


=item B<login> (<http://gbv.github.io/paia/paia.html#login>)

password). On success access token, patron identifier and base URL are stored
to a session file.

=item B<logout> (<http://gbv.github.io/paia/paia.html#logout>)

=item B<change> (<http://gbv.github.io/paia/paia.html#change>)
