Updating from older versions
----------------------------

IMPORTANT: If you are updating from an older version of EAGLE, please make sure
*********  you read the file doc/UPDATE entirely before
           working with this new version!

Tutorial
--------

The EAGLE tutorial in PDF format can be found in the /english/tutorial
subdirectory on the EAGLE CD-ROM.
If you have downloaded EAGLE from CadSoft's homepage you may also want
to download the tutorial file.

Sytem Requirements
------------------

  - Intel PC based Linux
  - Kernel version 2.x
  - libc6
  - X11 in at least 8bpp mode with 1024x768 min. resolution
    (800x600 with some minor restrictions)

Installation
------------

You can either use the RPM or the TGZ archive to install EAGLE on your system.
The following assumes that you have mounted the EAGLE CD-ROM as /cdrom
and are logged in to your system as user 'root'.

Installing the RPM archive:

  - Use 'rpm' to install the package:

    rpm -i /cdrom/english/linux/install/eagle-4.11e-1.i386.rpm

    By default this package installs to '/opt/eagle', but you can relocate
    it to a different directory using rpm's '--prefix' option. Note that
    a shell script will be executed that installs a symbolic link to the
    executable file in /usr/bin, and also copies the manual page to
    /usr/share/man/man1 (or /usr/man/man1, if the first directory doesn't
    exist). You can use rpm's '--noscripts' option to avoid this.

  - Enter the command '/opt/eagle/bin/eagle' to invoke the product registration
    (you need to have WRITE ACCESS to that directory for doing this!).

Installing the TGZ archive:

  - Create a new directory on your system (e.g. /opt/eagle):

    mkdir /opt/eagle
    cd /opt/eagle

  - Use 'tar' to extract the archive:

    tar xvzf /cdrom/english/linux/install/eagle-4.11e.tgz

  - Change into the directory that has just been extracted from the archive:

    cd /opt/eagle/eagle-4.11

  - Run the installation script:

    ./install

  - Enter the command 'bin/eagle' to invoke the product registration
    (you need to have WRITE ACCESS to that directory for doing this!).

Usage
-----

To use EAGLE you should create a working directory

    mkdir /home/username/eagle

change into that directory

    cd /home/username/eagle

and start EAGLE

Octagon apertures in Gerber RS-274X format
------------------------------------------

The various Gerber viewers on the market have different ideas about how to
display octagon apertures in RS-274X format. There all all kinds of
interpretations of the diameter and rotation.
When generating octagon apertures in RS-274X format, EAGLE assumes that the
viewer will interpret the diameter as the distance between two opposite
corners, and that it has to be rotated by 22.5 degrees to achieve the proper
alignment. In case your specific viewer interprets these data differently
you can adjust this to your viewer's special needs in the file 'eagle.def'.

IMPORTANT: Before sending data in RS-274X format to your board house you should
make sure you ask them how *their* software will interpret octagon data.
