+# OSSP macOS Packaging Utilities
+
+## What is ```launcher```
+Launcher is simply a tool that launches OSSP with the correct environment variables when inside a macOS bundle.<br>
+OSSP packages it's own runtime dependency tree with itself as to avoid dependency issues for the
+end user. To achieve this though, some hacks have to be made.
+OSSP needs some environment arguments to launch, such as ```DYLD_LIBRARY_PATH``` and ```LV2_PATH```
+to use the correct sysroot, and for the equalizer functionality respectively.<br>
+Normally, macOS sanitizes ```DYLD_*``` environment variables when launching a new program, so
+```launcher``` was made to create an entirely new environment pointer for execve() to use.
+
+## Notice
+NOTE: This does NOT bypass and/or exploit any security features of macOS / Darwin. This is an intentional
+feature, as when running 'protected' binaries (such as the ones found in ```/usr/bin```),
+macOS goes even further to sanitize the ```DYLD_*``` environment variables even when utilizing this method.<br>
+In saying that, there is ABSOLUTELY NO WAY this would EVER pass App Store verification.
+
+## How to use this?
+Firstly, build the launcher.<br>
+Then, build OSSP.<br>
+Then, copy the actual OSSP binary into the newly created bundle (Bundle/Contents/MacOS/).<br>
+Then, copy the sysroot from /opt/ossp into the bundle (Bundle/Contents/Sysroot).<br>
+Finally, make the .icns file for the app icon, and copy it into the bundle (Bundle/Contents/Resources).
