*******************************************************************************

This script compiles and installs a complete Build Environment for building

ReactOS.

User is not "root"

The default installation path for the Build Environment is "/usr/local/RosBE".

Therefore it is recommended to run this script as the "root" user. Otherwise you probably cannot create the necessary directories.

An alternative is to specify another installation directory at the installation process.

Do you really want to continue? (yes/no)

[no] yes
