NAME
     siril - image processing tool for astronomy and other applications

SYNOPSIS
     siril [options] [file]
     siril-cli [options] [file]

DESCRIPTION
     Siril  is	a powerful image processing tool designed for improving the sig-
     nal-to-noise ratio of astronomical images. It offers a wide range of  tools
     for aligning, stacking, and enhancing images from various file formats, in-
     cluding image sequences. It features a high-precision 32-bit floating-point
     engine and supports parallel processing to run quickly.
     The  application is divided into 2 binaries. The first one, siril, launches
     the program in graphic mode. The second one, siril-cli, is a  command  line
     interface allowing to execute the following options.

OPTIONS
     -v, --version
	    Prints the program name and version, then exits.

     -i conf_file
	    Starts Siril with the specified configuration file.

     -f, --format
	    Prints all supported input image formats, depending on the libraries
	    detected at compile-time.

     -c, --copyright
	    Prints copyright information, then exits.

     -h, --help
	    Displays a brief usage summary.

     -p     Starts  Siril  without  the  graphical user interface and uses named
	    pipes to accept commands and print logs and status	information.  On
	    POSIX systems, the named pipes are created in /tmp/siril_commands.in
	    and /tmp/siril_commands.out.

     -r input_pipe_path, --inpipe=input_pipe_path
	    Provides  an  alternative  path for the input pipe that receives the
	    commands if -p is passed. The pipe can be  created	by  an	external
	    program with the mkfifo(1) command.

     -w output_pipe_path, --outpipe=output_pipe_path
	    Provides  an  alternative  path for the output pipe that prints logs
	    and status updates if -p is passed. The pipe can be  created  by  an
	    external program with the mkfifo(1) command.

     -d working_directory, --directory=working_directory
	    Sets the specified path as the current working directory.

     -s script_file, --script=script_file
	    Starts Siril without the graphical user interface and runs the spec-
	    ified  script instead. Scripts are text files that contain a list of
	    commands to be executed sequentially. In these files, lines starting
	    with a # are considered as comments. If this option is  not  passed,
	    pipe operation is assumed as if -p had been passed.

     -s -   Redirects inputs written after - to stdin.

     file   Opens  the	specified  image  or  sequence	file  immediately  after
	    startup.

FILES
     ~/.config/siril/config.ini
	    User preferences that can be overridden by the -i option.

     /usr/local/share/siril/siril.css
	    The style sheet used to change the look of the graphical user inter-
	    face. This is useful for customization or if a GTK theme  is  incom-
	    patible with some colored elements of Siril.
