EAGLE is an easy to use, yet powerful tool for designing printed circuit
boards (PCBs). The name EAGLE is an acronym, which stands for Easily
Applicable Graphical Layout Editor. The program consists of three main
modules (Layout Editor, Schematic Editor and Autorouter), which are
embedded in a single user interface.

If EAGLE prompts for a license key the first time it is run, you can select
EAGLE Express option to run EAGLE as a free version or purchase a license to
unlock advanced features.

After the key is accepted, you may wish to change the permission of
/opt/eagle-VERSION/bin/eagle.key so that it is no longer world-writable:

  # chmod 0644 /opt/eagle-<version>/bin/eagle.key

This script installs the English documentation by default. Starting from
version 5.10.0, German and (some) Chinese documentation is included as well.
To select them, run this script as:

  # DOC_LANG=<xx> ./eagle.SlackBuild

where <xx> = "de" for German, "zh" for Chinese, or "all".
