System Requirements

This guide follows the UNIX style for all examples and screen configurations.

Users of other environments, such as Windows, can use this with a few considerations. For example, use the Windows style "\" as the directory delimiter instead of the UNIX style "/". Environment variables should also be changed to Windows style variables.
