Options

Play/Pause starts and pauses the simulation. This can also be done from the space bar.

Grid toggles the cell grid on and off.

Autogrow toggles the 'autogrow' on and off. When activated, the size of the board will be enlarged if there are live cells close to the edge of the board.

Status line toggles the status text which can be displayed along the bottom of the main window. This gives some information as to the current state of the simulation.

Snapshot board will create a .png image file of the board in the current working directory.

Loop delay presents a list of presets which affects the speed of the simulation. 

Rules allows the user to select from a preset list of birth/survival rules, or use the Custom rule dialog to specify one.

Zoom opens the zoom dialog.

Live cell color allows the user to select the color of a 'live' cell.

Dead cell color allows the user to select the color of a 'dead' cell.

=head1 SYNOPSIS

    golp [<filename>]

=head1 DESCRIPTION

This program will load and run Life-like cellular automata from .rle or .cells files. A good source for files is L<https://conwaylife.com/wiki/Main_Page>. It uses L<Game::Life::Faster> for the engine and L<Prima> for the GUI.
