=head1 NAME

pmgsh - shell interface to the Promox Mail Gateway API

=head1 SYNOPSIS

pmgsh [get|set|create|delete|help] [REST API path] [--verbose]

=head1 DESCRIPTION

pmgsh provides a shell-like interface to the Proxmox Mail Gateway API, in 
two different modes:

=over

=item interactive

when called without parameters, pmgsh starts an interactive client,
where you can navigate in the different parts of the API

=item command line

when started with parameters pmgsh will send a command to the
corresponding REST url, and will return the JSON formatted output

=back

=head1 EXAMPLES

get the list of nodes in my cluster

pmgsh get /nodes

574
575	pmgsh - shell interface to the Promox Mail Gateway API
576
577	=head1 SYNOPSIS
578
579	pmgsh [get\|set\|create\|delete\|help] [REST API path] [--verbose]
580
581	=head1 DESCRIPTION
582
583	pmgsh provides a shell-like interface to the Proxmox Mail Gateway API, in
584	two different modes:
585
586	=over
587
588	=item interactive
589
590	when called without parameters, pmgsh starts an interactive client,
591	where you can navigate in the different parts of the API
592
593	=item command line
594
595	when started with parameters pmgsh will send a command to the
596	corresponding REST url, and will return the JSON formatted output
597
598	=back
599
600	=head1 EXAMPLES
601
602	get the list of nodes in my cluster
603
604	pmgsh get /nodes
605
