=head1 NAME
cfgmaint - configuration tool for Visual Builder
=head1 SYNTAX
cfgmaint [ -rbxop ] command object [ parameters ]
=head1 DESCRIPTION
Maintains widget palette configuration for the Visual Builder.
It can be stored in the system-wide and the local user config files.
C<cfgmaint> allows adding, renaming, moving, and deleting the
classes and pages in the Visual Builder widget palette.
=head1 USAGE
C<cfgmaint> is invoked with C<command> and C<object> arguments,
where C<command> defines the action to be taken, and C<object> -
the object to be handled.
=head2 Options
=over
=item -r
Write configuration to the system-wide config file
=item -b
Read configuration from both system-wide and user config files
=item -x
Do not write backups
=item -o
Read-only mode
=item -p
Execute C<use Prima;> code before start. This option
might be necessary when adding a module that relies on the toolkit
but does not invoke the code itself.
=back
=head2 Objects
=over
=item m
Selects a module. Valid for add, list, and remove commands.
=item p
Selects a page. Valid for all commands.
=item w
Selects a widget. Valid for list, remove, rename, and move commands.
=back
=head2 Commands
=over
=item a
Adds a new object to the configuration. Can be either a page or
a module.
=item d
Removes an object.
=item l
Prints object name. In case object is a widget, prints all
registered widgets. If the string is specified as an additional
parameter, it is treated as a page name and only widgets from
the page are printed.
=item r
Renames an object to a new name, which is passed as additional parameter.
Can be either a widget or a page.
=item m
If C<object> is a widget, relocates one or more widgets to a new page.
If C<object> is a page, moves the page before the page specified as an additional parameter,
or to the end if no additional page specified.
=back
=head1 EXAMPLE
Add a new module to the system-wide configuration:
cfgmaint -r a m CPAN/Prima/VB/New/MyCtrls.pm
List widgets, present in both config files:
cfgmaint -b l w
Rename a page:
cfgmaint r p General Basic
