NAME
escher - interactive schematics entry program

SYNOPSIS
escher [ [-a<number>][-d <device>][-e]
         [-l][-m][-n][-p<string>][-q<number>]
         [-s<number>][-t<string>]
         [-u<number>][-w][-z<number>] ]
       [<template name>]

DESCRIPTION
Escher recognizes the following options:

-a  Autosave. An autosave is performed every <number> minutes. Default: no autosave.

-d  Select graphics device /dev/<device>..

-e  Suppress the default name when selecting change name.

-l  Do not display the line edit menu.

-m  Interchange the meaning of mirror_x and mirror_y.

-n  Enforce the displaying of all terminal and instance names.

-p  Provide default plot options.

-q  Set the minimum time for the display of error messages. Default: 2 seconds.

-s  <number> is the maze on the grid to which all input is rounded. Only valid in the circuit area. Default: 4. May be set to 1, 2 or 4 only.

-t  <string> will be used as the default basename for terminals used by the add and copy commands. Default: "term".

-u  Depth of the undo stack. Number is the <number> of commands that can be undone. Default: 10.

-w  Permit wires to run along instances.

-z  Error messages are replaced by the current template name after 10 seconds. Replace 10 by <number>.

The options are read with the function getopt(3). See the manual page for syntax of the options. An unknown option or an option requiring an argument but has none or an option with an incorrect syntax for number or resulting in a negative number will give an error message on stderr and cause an immediate termination of the program. The first template to be edited can be given as an argument.

PRIMITIVE CELLS
A library project with (default) primitive cells like transistors, resistors, capacitors and simple logic gates is contained by ICDPATH/lib/escher. To use cells (templates) from this project, the cells should have been imported in the current project directory with addproj and impcell (see corresponding manual pages).
