Overview

Package al implements Go bindings to OpenAL.

To avoid the requirement of users having to download OpenAL (or for developers to have to distribute dynamic libraries with their applications), this package works as a sort-of automatic 'installer'

The dynamic OpenAL-Soft library is packed as a binary blob within this package automatically for you.

When an application imports this package the installer will automatically run. It is not visible to users and only writes a single file to the hard drive *if it does not exist*.

Because OpenAL-Soft is LGPL licensed it is required by the license that users be able to run the application with their own version of the library, we are not lawyers and you should consult a lawyer to know in full if you are obeying the LGPL license of OpenAL-Soft when using this library, but:

You should simply inform your users where they can place their own OpenAL-Soft dynamic link library for their specific platform, file named as shown below, into their home directory under the ".azul3d" directory created on their operating system's file system: 

linux/amd64: libopenal_soft.so.1.15.1

And it will be dynamically linked and loaded instead of ours. Should the user wish to restore our dynamic link library, they can simply delete theirs and it will be automatically placed there once again.
