NAME
gschem - gEDA/gaf Schematic Capture

SYNOPSIS
gschem [OPTION...] [--] [FILE...]

DESCRIPTION

gschem is a schematic capture application and is part of the gEDA (GPL Electronic Design Automation) toolset. It is used to draw electronic schematics which describe the logical structure of a circuit. Schematics are made up of symbols which represent the various components in the circuit and are obtained either from a standard library or created by the user. The connections between components represented by nets (wires). Schematics may be exported to PDF and PostScript files for printing or to other output formats for further conversion. Output to various image formats is also supported. gschem can also be used for editing symbols for use in schematics.

OPTIONS

-q, --quiet
    Quiet mode. Turn off all warnings/notes/messages.

-v, --verbose
    Verbose mode. Output all diagnostic information.

-r, --config-file=FILE
    Specify an additional configuration file. Normally gschem searches for the system configuration file, then `$HOME/.gEDA/gschemrc', and finally for a `gschemrc' file in the current working directory. This option allows the user to specify an additional rc file which is read after all the other rc files have been are read.

-L DIRECTORY
    Prepend DIRECTORY to the list of directories to be searched for Scheme files.

-s FILE
    Specify a Scheme script to be executed at startup.

-c EXPR
    Specify a Scheme expression to be evaluated at startup.

-o, --output=FILE
    Specify a filename for PostScript output. This command line argument is useful when running gschem from a shell script and with a Scheme script. The filename can be changed through the print dialog box.

-p  Automatically place the window. This may be useful if running gschem from the command line and generating output.

-h, --help
    Print a help message.

-V, --version
    Print gschem version information.

--  Treat all remaining arguments as schematic or symbol filenames. Use this if you have a schematic or symbol filename which begins with `-'.

SCHEMATIC AND SYMBOL FILES
Optionally, schematic or symbol FILEs may be specified on the command line. Any schematic or symbols specified are loaded at startup as separate documents in the schematic editor.

If no FILEs are specified, a blank schematic is created for editing.

ENVIRONMENT

GEDADATA
    specifies the search directory for Scheme and rc files. The default is `${prefix}/share/gEDA'.

GEDADATARC
    specifies the search directory for rc files. The default is `$GEDADATA'.

GEDALOG
    specifies the directory to which to write log files. The default is `~/.gEDA/logs'.
